One thing to remember is that the more power the vehicle has from the start, the more power is going to be gained, a 5% increase in HP on a 140 hp motor only 6-7 hp but on a 450 hp 23-24. Also, for the viewer that stated how the CAI would mess up the fuel ratio due to more air, its not necessarily more air that makes people put in the CAI, its that if you get proper separation and can suck up cold air, that air will be denser theu your car will have better combustion.Thats why your car seems faster in the cold weather, especially turbos
I noticed this problem too. I removed the box, attached heat sheilding tape to the backside, paying special attention to gaped areas...problem solved. It also helps if you cut the padded insulator on the hood to fit perfectly around the rubber on the box. This seals the area really nice. You should also install a 180° thermostat just for good measure. I live in texas.
The problem with the focus and other compact cars is that there isn't enough separation between the intake and the engine. In a larger truck, I've found that these intakes perform better.
When you mess with the intake doing a mod you may have to cold start the car and run it for 15 mins or so on idle without reving. This allows the CPU to recognize the mod then take it for a short 5 min drive and park it up to cool down a bit then go from there. Diffrent cars will vary in this process but it may be similar?. The idea is that the CPU re-learns its self and programs to the new paramiters. I would think that a basic inlet mod or exhaust mod could be corrected this way or similar. Any larger mod may need professional programing.
It's refreshing to see someone admit their mistakes. A little advice though: I've never seen a K&N, or any brand filter for that matter, make a NOTICEABLE difference to power in anything but an extremely high-performance engine. If there is an increase (and that's a big if) it's usually just such a small amount, it's basically within a margin of error and certainly not noticeable. The other thing to keep in mind with these kind of filters, when they are tested on dynos, they are always new filters. These kind of oiled filters tend to degrade quickly over time as particles get caught up in the oil. This is, of course, what they are meant to do, but it also means you need to clean them frequently to have any hope of maintaining even that tiny performance improvement. With this in mind, I highly recommend getting a non-oiled air filter from either the manufacturer or, if you really want aftermarket, someone like Wix, which has been shown by independent testing to offer that balance of awesome filtering (which is why we need an air filter) with decent air-flow.
I have a K&N on my 2016 Frontier Desert Runner and it helps mpg/hp little and the truck runs smoother but also have performance exhaust system to work with it so that maybe why
Yes. Most people don’t realize that all cars come with a cold air intake. The aftermarket ones become heat soaked pretty quickly. Just changing out the filter works the best. Great Job.
I recommend cleaning and re oiling your air filter at the interval your auto manufacturer instructs you to check your air filter. I have always done it every oil change(5000 miles). I ran k&n for 175K in a Tundra and 170K in my wife's Highlander.
I really like your point about the standard Cold Air Intake filter and the engine heat. It's logical and makes clear sense, and putting in just an upgraded version of the same filter type for your car I'd ALSO SECOND as a high recommendation. I put a K&N Filter that was the same size as the OEM on my old 2000 Chevrolet Blazer LT 4x4 4.3L Vortec and noticed a significant difference in throttle response. I had also replaced the MAF sensor shortly after due to the grease and all from the filter and also then noticed more improvement. Even the filter by itself made a big improvement in engine performance. Understandably, this may not work for all cars but is definitely worth a shot.
K&N filters give tiny increases in power and torque. What they do generate a lot more of, is fuel efficiency. By running a cleaner through my FJ cruiser gas line and engine, then adding a K&N filter I've gained about 80 - 100km from when I first purchased the vehicle used from a dealership.
You will get what they call a "can tuned" if you install a CAI without a tune.....but if youre adding mods that means you obviously wanna make more power so thats why a tune is vital if you wanna MAXIMIZE your gains.
Thanks for doing the video, really good feed back. I guess the KNN short ram intake will work differently from car to car. I’ve had one in my 2019 Civic 1.5T for about a year in the Northeast and I did not get a drop in performance in hot summer days. I love the sound and noticed throttle and mpg difference. Plus clocked a 3 tenth of a second quicker time to 60 MPH.
I put a K&N in the stock box in a Focus SVT. Works really well. Heat under the hood in these things is a big problem. My wife and I both have them and the heat cooks sensors. With these cars it becomes an effort to get airflow into the engine compartment to reduce the heat.
Hi, Fuel Trims on an ecu are responsible for compensating for the extra air that comes into the engine i.e the air fuel ratio will automatically be corrected by adding more fuel to achieve 14.7:1 in closed loop control
cold air intakes work with forced induction engines (turbos and superchargers) don't expect a Ford Focus became a Fast and Furious version only installing a K&N intake man!
To everyone that says it's a waste.., I dynod my 2013 focus SE 5 speed after I got it. Pulled 152 bone stock (sport suspension from factory is only upgrade on the car). I put in a K&N intake just like the one mentioned, I was then pulling 168. I got a 2.5"catback custom system from a shop local in salem, OR. (Used pieces from a Borla setup) sadly did not get to dyno with just those two upgrades. Finally got a tune from Tom (focusfinatics helped me find it) After everything was turned it then pulled 173 on the dyno. It's not a "30hp" gain like some people say, (maybe with a larger throttle body idk) but it is very noticeable. Hope this helps some of you looking for mods out there. (Spent about $1,1,80 total on all mods after a mail in rebate)
No way this power gain of 16 bhp is real. There are Pub figures and wet dreams......... and there is reality. Yes 2 healthy cars can vary by 3-5 Bhp and if running same map and settings it is that close. A better Exhaust can help breathing so can filters but valve size inlet tracts injector size flow rate dwell timing and a rising rate fuel pressure regulater all contribute. but there is a maximum a stock engine can produce by its design. If you change more items on the engine that scope for more tuning increases and so on, every tuned engine has bottlenecks by its design no magic maps can circumvent physical limitations. I dont wish to debate this fact of engineering. people can believe what they wish to believe. I once tuned an rs turbo escort in the 90s Many times in the process did I reach bottlenecks. and until that was removed power would not increase. all mods need to work in harmony a new intercooler painted black helps a heavily modded car massively but on stock very little difference. I used pub figures once too 25 -30 yrs ago. At 54 yrs old I now only deal with reality. My current car An RCZ R runs 270 + BHP 1.6L stock engine, exhaust, and filter plugs etc. its designed to run that. My Rs turbo also a 1.6L took 2 yrs and £4500-£5000 in mods back in the 90s to reach 260 bhp.
I put an airaid “cold air intake” on my truck. After about a year I decided to put the stock air box back on with an k&n drop in filter and I left the airaid intake tube in place of the stock intake tube. I did a 0-60 before removing the cold air intake and after reinstalling the factory air box and there was less than half a second of difference in the 0-60 times between the two. So I left the airaid intake tube on in place of the factory tube, left the factory air box with the k&n air filter and sold the “cold air intake”. I now have an aem Filter instead so I don’t have to worry about oiling the filter like the k&n.
I used to work for K&N, there is no way they told you that you need dyno numbers. Plus, if you bought it from Amazon you should have called them first.
Well. It works darn good on my 04 Sierra 4x4. ! Sounds great. Lots of pickup when you stand on it. But the 6.0 L Is notorious for its lack of mpg! I get 12.2 average now. Got 10.8 before. So if mileage is your concern. That’s what you should expect!
Ann Onymous Give me proof. I’m assuming you didn’t get the engine re-tuned or you didn’t put an aftermarket chip in it. So that air intake just turned into a expensive air filter
About 15 years ago, a BMW race car engine rebuilder and BMW race car driver told me the same thing. Don't put an air intake system on. It's worse than the factory setup. Drop a K&N filter into the stock air box instead, and I have been doing it ever since.
I had BMC which worked only for 10k km and couple of years even with oiling at recommended intervals. Now, no matter what I do it's not giving me the same performance as it was new. My car feel sluggish at lower gears and screams in high rev in a bad way. Moved to stock and the engine feels super smooth.
I bought a k&n intake for my 10 Chrysler 3.6 gained power and car been doing very well for about 3 years through all seasons now plus i travel in it ..
You will get heat soak either way, the sheet metal baffle isn't to prevent heat soak, it's supposed to slow airflow from all areas except the oem pathway through the fender or front grill. Good outside airflow will negate the engine bay heat so maybe it's that the shape of the baffle didn't seal well. Also when you take off the oe air box you detuned the wide band nature of the intake and turned it into a narrow band WOT peaking unit at best.
You must modify the exhaust to get some hp gain with the CAI or SRI. Ok another question. Where is the cooler air coming from when the air filter is exposed to the heat coming from the engine? No one has answered that question yet and I don’t think no one ever will answer it. The best thing to do is modify your stock air box to get cooler air if you can. I did it on my 2002 Pontiac Grand Prix SE. I took out the tubes and cut the barrier out. The box is right behind the left headlight and it gets plenty of air.
Install a brand/unit with a housing (not an open shield) for the filter and also one that connects to the original air ram. The car's air ram sucks in cold air from the outside and farther away from the engine block. MST, AEM are some of the manufacturers that includes an air box (not shield) and retains the original air ram of the vehicle. Also, replace your cat back exhaust with larger piping to optimize your exhaust system with 5-15 hp gain at around 5000 rpm, which is good for merging and overtaking maneuvers.
Wild. I got mine and dropped it in, when it was hot out, noticed mild gains ish, and much better noise. But on dyno, got 6.1whp more than stock at top end, but even down low at 3000ish rpms, still 2whp higher,
The only thing K&N that goes in my hood is a high-performance K&N filter with stock intake. It's a lot cheaper, and you do get some power increase going that route as well
If you run around at 6,000 rpm you might feel some difference. normal driving NO. KN users rarely ever clean their filters. KN/ other reuseable cold air filter systems are designed to separate a fool from his money.
Just changed to a K+ N canister filter. Not the pipe one. On my 2017 Titanium Escape 2.0 turbo 4 cylinder. Makes a big different in sound and a little power gain off the start. Didn't expect the engine to run like a scaled Dog! But for the $60.00 bucks it does what it said. Thinking about a less restricted exhaust system. If the price is right. In stainless! Just for a better sound and look. Shawn
The standard K&N air filter (non-cold air filter) are great on manual vehicles due to adding a small amount fuel milage….its not meant to add more horse power! I do have a 2012 Chevy Cruze Eco 6 speed and I did gain 4 miles per gal on the fuel economy which is what I was looking for! Just remember….any tine you use new products on your vehicle, always research the product line and the type of vehicle its going into before making a purchase! This will save you time and money and keep you on the road longer.
From what I've read and heard, the "Cold" Air Intakes are for hotrods, and if you don't work up the rest of the engine, it won't do anything. If the sound changes, there is definitely a change in the airflow however, 'cuz duh... Yes, thanks for the trial. I think I will skip putting one in my Suburban unless I need to replace the catastrophic converter(!) 😯 (At that point, I would put low restriction exhaust in.) Every Dyno Test I've ever seen showing improvement for any cold air intake has been paid for one way or another by the manufacturer, but I don't get out much. 😝
To get the best out of a Intake, you need to pair it with a high flow downpipe, and a 70mm+ stainless Steel exhaust. And of course a tune, so the car takes proper advantage of the mods. An Intake just by itself is basically just a sound mod
Unless you get truly cold air, have a piggÿback module for the MAF or ecu tune to adjust the A/F ratio. it's all just looks and noise. You will see some better throttle response but you can get just as much with a throttle body optimization.
What you did is the same as I did. The K&N filter does it all. Me like you didn't reallly like the cold air system by K&N and I saw a power loss to the engine. Left it on and tranded trucks. After I traded, I found out things the the Ford was a bad year and then I was glad I changed trucks. I in the last truck and this new one, I only used the Expensive K&N filter and got the same results that they claim. Works the same as a cold air system. Does the same also.
I have had a K&N cone filter on my 2104 F-150 Tremor 3.5 EcoBoost since it was new. I noticed Gas Milage drop recently, and just today cleaned and re oiled it. I will do the re learn trick also.
For my truck I got an Air Raid Intake system and kept the stock air box and got a drop in AEM dry air filter, no problem with hot engine air coming in with a bit better power and fuel economy, and the truck doesn't stall anymore.
I put this same system in my 2017 Toyota corolla, I live in central Texas where it gets 110 degrees every summer. I saw no difference from any season, the only reason you will be losing power is if your losing air, such as the filter not being tight enough. Sure of course its better to have cold air, but the only consequence of having hot air instead of cold air is loss of fuel economy, but the major factor with that is your driving habits, however as long as everything is tight enough, you should be just fine as far as power goes.
I think you meant short air ram. True Cold air intake gains on the high end. While short air ram gains on the low. Agreed, that short ram with weather stripping semi enclosures or no enclosure risks hot air engine bay seepage. I recommend short air ram with full enclosure or excellent seals.
Good, honest review. I was thinking about getting a cold air intake for my 2012 Dodge Ram 1500 5.7 Hemi, but after seeing this review I'm going to take a pass on that.
Thanks for the feedback because I recently installed a K&N air filter on my 2012 Focus SE. I did notice immediately a noticeable VROOM sound and a low end growl. I haven't put it on the DYNO so I don't know exactly how much boost I got from it. I will point out that it never burned rubber before like it does now. Based on what you told me, I will watch out when the weather becomes hot.
From experience,it's much cheaper in the long run to just buy the drop in filter from K&N and add a catback when your OEM exhaust need replacing.I just got rid of a cold air intake in fear of it sucking in water in heavy rain because part of the fender splash shield is broken off, exposing the filter.
I have one installed on my truck with an aftermarket exhaust. I see power improvement and mpg gain. Not by much, i noticed 2mpg gain. I installed it over the summer with average temp of 80-90 degrees. It didnt hurt my truck
No you don't. You think you do because that's what you expected to see. But no you don't. It doesn't change the computer programming. And before you get all in a huff and your panties in a twist, I also have an intake and exhaust on my truck. Runs exactly the same, no performance or gas mileage increases. Sounds nice but nothing else.
King Daniel maybe it doesn’t increase power and mpg in every application but people have ran dyno tests before and after there is a video from JEGS on RU-vid they gained 14 hp on a Chevy 5.3. Plus a lot of people notice gains. But I guess they aren’t as smart as you and they’re probably all full of shit.
Okay, let me explain this one more time since you're obviously slow. Everything is run by computers, the air/fuel ratio, injection rate, spark, everything. Bolting something on does not change the computer programming, thus you gain NOTHING. There is no power or performance increase unless there are changes to the computer parameters that control those functions. I don't care about some bs marketing video you've seen about a product someone is trying to sell you. Any gains are hypothetical, and implied at best, unless you get ALL the equipment to facilitate those changes i.e. a programmer.
K&N’s DO offer slightly more horsepower over a standard paper filter. If you still want the cold air intake noise that you got from the K&N, then you need to get a performance air filter that is already housed within a heat shield enclosure. I used to have the same Focus and I put a performance air filter (like K&N) in mine and it was enclosed in a carbon fiber shield and it worked great! Smoother and more peppy acceleration and it sounded great and heatsoak wasn’t a problem! You won’t get any of the intake sound from a panel filter...K&N or not...trust me! Part of that noise is caused from the filter sucking the air in. The panel filter gets enclosed in the air box and so it deadens the sound. 👍🏼
So if I add a cold air intake, do I need the shields around to keep the heat out? Is it mandatory? Because it’s cheaper without it but will it still make a louder sound even with hotter air than normal?
I bought the intake for my 2014 Chrysler 200 2.4 and took it out a week later because it was to loud! I have it 4 sale for $300.00 have everything for it! I'll install it locally!
Maybe in your stock focus you can't feel anything. But, I have a Mustang GT with a Ford Racing intake manifold, a 24 pounds fuel injectors, MSD ignition coils, headers and, really trust me, the K&N intake really work.
Cowl induction..ie.- 'Poor man's supercharger'..that works! However,not usually. Cowl induction ( when installed as an air tight plenum) only begins to function well over 75 mph. But for long-hual driving on the Super Slab, Oh Yeah!
I had that when i owned a mazda 3 2016 , and it made such a big difference in gains and throttle response..I didn’t have a bad experience, i guess I’ll be installing it even in my ram 1500, i think the way they made it for the ford was bad to begin with..
I would add a thermal tap or wrap on the pipe and the engine side of the shield to add extra isolation from the engine if that happens. On the other hand you should look at a cold air that is a fully inclosed box with a directed inlet for air to really limit the hot air form the engine
Put he K&N on my Previous Edge Sport....what a $350 waste of money. All I noticed was that it was extremely loud but with no discernable gain in power . On my new Edge Sport I went with a filter replacement and didnt fall for the hype
@@andrewkjeldergaard9653 and it didn't go through the other filters as much as it did with the K&N Unrealistic test but still same condition for each filter
Main question is: Did you have the AC run inside your car while you were driving in the more heated temperature times? Because from what I’ve learned and key word “I’ve” is that when you have a K&N filter in and it’s on hot days you’ll need to run the AC to keep the car cooler. For example if you made a tuner car for drifting(RWD cars). While your drifting you’ll want to have the AC because it’ll “HELP” the car engine stay cooler and not overheat. Again this is from what I’ve learned and my knowledge on cars from being taught,self taught, and still learning more about cars. I mean also you put a cold air intake on a new model car which will also affects the car and it’s warranty’s you have on there or whatever
Kayvon Young - Thank goodness you said that you´re learning. ;-) How in the world imposing more effort in a running engine will make it stay cooler?! You realize the AC is just another power hungry system the engine as to drag along while running... So by all means keep learning. Physics 101 is a good starting point. As of right now you´re surely on the wrong direction. ;-) Cheers
At least this guys gets it in the end. SO many people pay big money for these stupid things that suck up hot air. If you had a turbo or supercharged engine, it makes things even worse. You get detonation, the car pulls ignition timing and you make less HP. For a lousy $10 I took a factory air cleaner box on an 05 IMpala SS, gutted out the baffling then cut a 4" hole in the side with a hole saw,attached a 4"x18" rubber duct hose and ran it through a hole in the fender, sealed any openings with furnace duct tape .The only air coming in is from the outer fender. No engine heat. Depending on the temp that day, you can see a significant drop of air temp on the IAC sensor. Cant imagine what that sensor reads with an open K&N set up that doesnt totally seal out the engine heat. I suppose in a lot of cases, the stock set up beats that K &N shit IF the kit doesnt seal the filter completely.
I did an AEM drop in dry filter in the factory box and an Air Aid intake tube in my Dakota. No worries about heat soaking with a bump in performance and no more stalling with the factory resonator. 🙂
FYI...when they test CAI they are in a shop on a dino with the hood open with a big fan blowing on the front on the car but other independent tests have shown CAI don't work and in some cases lower hp and they will increase your air intake temps.
Correct, long term & short term fuel trims are adjusted by ecm that gets its data from various sensors one being the mass air flow sensor that sets the fuel mixture to lean or rich depending on the amount of air, temperature, rpms, throttle position, etc. So basically no matter what you do the ecm is going to adjust the fuel mixture back to optimal ratios for emissions, unless theirs a fault or failure. Cold air intake in the same location as the factory air box generally want provide any benefits other than sounding tough. K&N knows that too, but they have a business to maintain along with a lot of other parts sellers. Was different back before the electronic control cars then just flipping the the breath too upside down would let a little more cooler air in & reduce restriction into the carb & sound tough, but those where fixed fuel ratios & you could (sometimes with a little modification) adjust the mixture leaner or richer for better performance.
So I putt a spectre air filter. On my 13 focus with 186000miles . OK i lost MPG after installing from 27 to 23 in city but I also have code P0420 wich im fixing RN ... And yes I'm a heavy foot driver.... On the other hand the car is running more smoother and drives smoother, when accelerating I can feel a lil more power wich in my case I think it's worth it.... And the sound is amazing as well.... In my experience I think it's worth it for the money your spending if you want a smoother and a lil more push on acceleration....i will keep yall update....
In my opinion K&n gives you like 2-5 extra hp because they alredy tested with dyno. The problem is If you want to leave the Oem intake plastic tube, you can't feel a lot diferrent, also you need the basic combination what i got, exhaust 2.5, high flow cat, injen cold air intake tube with K&n filter, aem bypass. Tune. The first's 3 upgrades
I have a 2017 Ford Focus SEL and I installed the K&N cold intake and it works fine. I noticed that you have a manual transmission but mine is a automotive sport transmission. That might be the difference. Because my Focus is pretty quick after I installed it and no problems.
Hey man, I really appreciate the update video, and glad to see you learned something. I wish I had seen this video before I commented on the original video on this subject. However, go ahead and take a look at that comment. It will provide even more insight into why you experienced what you did. Us old farts are already aware of these things, but then again, I've been working on cars for over 35 years, including today's modern cars. I have a 2012 Focus with a stick too, and I LOVE it! Keep up the good work!
I've enjoyed my aem Cai, I just cleaned the filter so performance should pick back up, my car was throwing emission code because it was so dirty ultimately affecting the performance, I also had a tune.
The k&N regular filter gave me a little hp. I don’t have Peg my gas pedal. It does provide better and stable MPG and if I’m driving sportier the MPG doesn’t go down as much than factory filter.
I have that K&N engine air filter in my 09 Camry,2.4L engine and it runs a lot better than it did with the stock air filter. And I don't hear any un-wanted engine ,air intake noise🤔🙂. But then I don't drive a Ford😐....
need the exhaust ( borla ) to balance extra air intake. don"t pay any attention to this man. you need someone that knows more about performance. to get that extra, you need to spend that extra.K&N cold air box,with a true sealed air box. cost about $400. exhaust about $1295. hwy. mpg,went from24 to29+, hp from 280 to 310, yes this made a big improvement. 2004 FORD T-bird 3.9L-V-8

Saw updated video...thanks. You look like a decent guy and well just like me we learn the hard way...I like the panel filter but bit worried about oil on mass airflow sensor...thanks for update
The PCM will work around the K&N filter, NOT the other way around. People who say you need to "retune" a vehicle to accept a CAI have obviously never heard of elevation and sea level. K&N sucks in more air, the PCM realizes this and adds more fuel, more air & fuel mixture = more power, plain and simple. As far as MPG's goes, most CAI's actually give you less MPG's due to the air/fuel ratio.
the issue is the car needs a tune for the intake it self. K&N will say it can be used without any other mods. but if you want it to run properly a TUNE will fix this issue plus youll get more out of it.
I regularly see issues with intakes on customer cars. Here's just a few. 1: silicon content in the oil is much higher in cars with k&n style filters. I have sent out oil for testing to verify this. This means substantial wear on internal engine parts. 2: fuel trim issues on cars with Maf sensors. This is very common when the intake tube is changed, due to different diameter or bends of the tube. It can cause a lean or rich condition witch can cause power loss, wear, fuel mileage problems. 3: Gains HP in high rpms, lost torque in low or mid-range rpms. So you basically take away the acceleration you want in a daily driven street car. 4: Wasted money because there is no difference besides the noise. Even if you "tune" your car for the intake, there is usually no noticable power gains. The power increase comes from the software and would have done the same without the intake. An intake should honestly be the last thing you upgrade, because most OEM intakes are capable of more flow than your car needs. Start looking into an intake upgrade when you make a large change, like a turbo, supercharger, etc. And never believe the dyno from the company that sells the part. I have personally dyno tuned many cars, and they usually make the same power or minimally more (1-5hp) but will almost always loose more torque down low and make your car slower.
@@daevid21 if you can achieve 30 hp with an intake exhaust and tune, you can most likely achieve those same numbers with just a software tune and catalytic converter delete. Catback exhaust is useless, just makes noise, And intakes are useless and just make noise. Unless you have some serious power mods like a turbo or supercharger, you will not have anything to gain from full exhaust or an intake. A 1xx hp focus does not stand to gain anything from and intake or exhaust. A tune? Sure, you can pick up a little bit.
@@Josh-py2in Theres usually no power gain from intake and tune?? Well thats wrong, but im too lazy to show how stupid you sound saying that. Ktuner or Hondata Tune and a Intake with a Civic will have massive gains. Speaking from experience. And 2-8hp gain from intake and depending on motor.
@@Rob_Nasty gains from a tune, YES. Gains from an intake, nothing or minimal on most cars. Even when you do gain hp from an intake, it's way up in the rpm range and it will usually loose torque in the mid to low RPMs. I actually dyno tune cars using Winols and mpps. Intakes are litterally the biggest waste of money in the car world. Everyone in a Honda adds an intake and suddenly think they gained a lot. In reality, on a dyno, they gain maybe 5 hp at 6500-7200 rpms and they loose what little torque they have at 4000-5000 they loose a substantial amount. You want real power, water/methanol injection with a tune, or e85 with a tune, nitrous with a tune. An intake is wasted money and just makes noise 90% of the time. Tunes make power, intakes just support power. Until you learn that, you will forever be in a slow car.
@@Josh-py2in I run turbo so low end torque is amazing for me. But yes now were talking!! High rpm gains exist with intake and or tune, for every car the scenario is different though. But theres no doubt intakes work. PRL has their dyno show mod by mod dyno'd numbers, and the increase is real, even if its minimal. And yes there is other massive gains out there. But those gains people never go for inless their a real car enthusiast.
