0:45 "The power curve is really wavy, it shouldn't look like that on a 911. It should be much smoother" 3:00 "These engines always have a wavy line, I'm not concerned" Damn Charlie, make up your mind son!

Let me do a translation: "Oh so you've cleaned the injectors, replaced the cats, and exhausted all the options I was planning on fixing this wavy graph. In that case these engines are meant to be wavy like that"

Don’t forget aftermarket filters don’t filter as well ( 75% vs 99% for original ) as original filters and can screw your maf if over oiled.

@John_cupra290 5 лет назад

I drive an f56 mini cooper s which with the oem filter actually hit 208bhp & after fitting a k&n panel filter dropped to 198 bhp but with such a negligible drop the increased noise ,especially windows up believe it or not was well worth it &im convinced the throttle response is improved and there really does seem to be more popping on the over-run! I have an induction kit en rout & am really really interested to get it dynod again &really try put this to bed once & for all, awesome content. Cheers

@badBikerz 5 лет назад

When you first put the bmw on dyno at 6:00 I was noticing how steady it was and just then you said that a nice smooth curve I was noticing how steady the car was on the machine itself. Seemed real smooth. Nice video thanks for posting. And yes it seems these usually give some slight power increase but mostly people keep them on because like them I like the sound better.

@hemmarket 5 лет назад

I installed the K&N filters in my Macan S, which require powerwashing and oiling yearly, but I too didn't really see a big upgrade. The COBB tuner, which remapped the ECU, did make a big difference on the high end, put not so much on the low end where I wanted to see gains. It also eliminated the exhaust sound, which as you say, is really a big part of owning a Porsche ! I reset me car back to factory settings, and returned the tuner, but the filters remain. Thanks, well done video !!

@reecedrury4145 5 лет назад

The panel filter should always be seen as a supporting mod when pushing on further. Probably see benefits post exhaust and remap.

Get that IMS done if you are worried. When I bought my 986 S it was on its way out and I put the LN ceramic ball bearing in which had a lifespan of roughly 75,000 miles. I could have done the direct feed but ceramic was cheaper and 75,000 mile rating is fine by me. And I have a 6 year / 50K mile warranty on the new bearing. Can’t go wrong with being safe.

@NZsarge1 6 лет назад

In addition your aftermarket filter is (should be) serviceable where paper elements aren’t, they’re throw away item which cost you every time a services due. If you replacement paper filters aren’t that expensive then whatever you like but it’s it’s a high cost item then a good quality serviceable aftermarket filter is worth a look.

@eveythingthatsadam Месяц назад

The engine has been tuned to run with the standard filter from factory. Unless you are doing a remap, there is no point in getting a k&n or similar

@guyroberts9963 4 года назад

I have a 997 Carrera. Fitted a K@N and for a about 2 years I kept chasing an check engine light. Multiple issues, including vacuum leaks, but the final fix was to put back a standard air filter and put in a new mass airflow. My understanding was the oil from the filter can contaminate the MAF. Either way, this caused my engine check light so beware.

@club0 5 лет назад

I put a K&N performance filter that has an extra air intake "hole" on my 1.6 ecoboost and measured before/after figures through OBD and the kn increases the turbo boost by several PSIs and improved throttle response and sound. I was surprised with the outcome on my car.

@xrbperformance4290 6 лет назад

This is interesting, you should do more videos about this. You have mention the Leon cupra(s3 & golf r) is a performance bargain, how would that be improved with just a quick remap which bumps the power up to 360hp and equivalent torque? Or would it just make it un drivable ?

@Mogsy28uk 6 лет назад

i only use K&N or Pipercross filters, they work, save you the cost of replacing the paper one each service (just wash, dry and re-oil once per year), and as you noticed, better sound, especially the models that have the rubber bung at the side (remove bung for warm fuzzy feel). :)

@funfun5656 2 года назад

The IMS is not as much to worry about if you're regularly running the engine at highish RPM. That's because the bearing was designed to be lubricated when the oil pressure gets nice and high and your oil splashes around with some obviously making its way into the bearing. Like any bearing (as opposed to a regular transaxle) the IMS does not like to be spun while dry.

@RobManser77 Год назад

I used to own a 328 Sport Coupé just like that - also in Forest Green, I think it was called. I'm on my 7th BMW and have driven many more, and the 328i remains my favourite. One of the last with a cable throttle, which plays a major part in that opinion, but they were also pretty light (same weight as the 996 - around 1300-1400kg). You also didn't get a clutch delay valve or any nannying electronics - just enough tech to make it a good car.

carwow Would a low rev turbo help to filter out the wavy power curve maybe? Also your car power peaks at almost max rev, so a low rev turbo could be a good investment for higher torque at low gearing offering smoother rides... I think.

@Broadizzlz 5 лет назад

For these older 911's, should keep the new filter and alter the funnel/opening of the pathway from the rear deck lid to the intake box. If you lived in the states, getting away with High-flow CAT upgrades would be ideal - and a decent tune.

@adamblaknovski279 5 лет назад

Run some expensive fuel system cleaner or ATF in the fuel to clean the combustion chambers, intake valves and injectors, then change the fuel filter. Most of the restriction comes from the intake tubes so unless you change the intake to a proper cold air intake system with exhaust mods and get it tuned to match you will only mess up the tune and lose power. High flow filters all let more dust through so the cost of your "sound modification" is reduced engine longevity.

I've also tested some air filters on my M3 on the Dyno. K&N is the best of the 3 I've tested. I had a K&N filter, an OEM BMW filter and a BMC filter. BMW and BMC delivered the same power. The K&N gives 4hp more! I think he uses also BMC, it looks the same style as my BMC..

@Willadin 6 лет назад

Some drop in performance filters save you the need to replace them as often as paper filters. Just need to keep it clean. Maybe a tune will help with the gains from that mod but it may also depend on the car.

@zfloz9895 4 года назад

Love this 911, I have drove one , witch hade soft tuning, was accelerating so brutal and nice. For that air filter, you should had to drive the car for at least 20 miles, so that the computer can make the fuel trimming adjustment. Otherwise, he would not know ,what's with the sudden changes in the air volume.

@eleonik76 6 лет назад

Okay,so here is the thing. I have played a lot around with aftermarket sport filters like K&N,Pilot,etc.. From having experience with Accord Type R,Galant VR and BMW 525i,i can tell you with certain,that the higher you rev the engine,the more you feel the benefits of the sport filter. No,it does not increase your HP.,it can't do that. But allows a better air flow which results in better throttle response and better performance at the high revs.

@SK-uq8mm 6 лет назад

S.T T. So what performance is it giving if there is no hp upgrade or nm upgrade

@eleonik76 6 лет назад

J Alcatraz As I mentioned,the performance is not defined only in HP or Nm. Almost all cars come with restricted air flow. To understand what I mean,put a cotton ball in one of your nose holes and run. You can keep the jogging,but if you take a fast sprint,you will find out why air flow is so important.
