I Made My Twin-Turbo V12 Mercedes Sound Like A FIGHTER JET With A Prototype Intake! CL65 AMG! 

Check out CL65 AMG Snow Drifting right here! fb.watch/beg6R9tyty/

Perfect timing for another glorious V12!

I really like what you’ve done to the car this far, especially fixing and keeping the ABC. There is on but though, the new intakes took something away from the V12 beauty.

No way I’d be willing to lose the carbon fiber cover and the AMG builder signature. Too boy racer for me…

For the door controls it is the main box behind the door panel that most likely has a corroded circuit board. Mine did and I removed it, opened it, dried it and oiled it. Works like a charm.

Every time I watch you with your cl 65 it makes me so happy that I sold mine! THANKS!😀

New airfilters make it look kind of a "cheap". Keep it classy, keep it OEM.

I’d pass on the intake. It would be a shame to discard the AMG cover and carbon fiber trim just for some extra under hood noise.

Eh, the idea of a new intake is good, but I think it is always more classy to be able to keep the engine covers and such. Plus, one of the luxuries of this car was how quiet it was.

Loving the Mercedes content. What a complicated vehicle. Thx for cutting the pump open.

Finally! Thanks Alex, I really only watch your Mercedes content. I think you can find way more power on the CL v12 than previous tuners who just add heat exchangers/pumps. You’re best mod before you go to Dyno will be meth injection.

As for those intakes... man, that's a hard no for me. All that hot poorly filtered air going into that poor engine. No.

What you gained isn’t worth losing the clean look of the engine bay with the covers

Alex, I love your videos. No click bait half done 'next time' stuff. You just say it how it is. Thanks for your content.

Everyone I’ve talked to that’s converted to coil overs has absolutely regretted it. Even the mechanics that have performed coil over conversions say their customers hate the way the car rides. ABC is expensive but it’s an incredible suspension.

Your CL65 AMG are the most anticipated videos for me! Thank you for the ever entertaining and educational content!

I have a CL600, same car, not AMG. One of the things I like about is that it is extremely fast in silence. Adding sound doesn't suit these cars in my opinion.

I’m super grateful for the ringing bell ! I was actually in Chicago a few weeks ago for a convention downtown. I wanted to look you up but I didn’t even know where to start ! I’ve been a subscriber since the beginning! You really inspire me ! Thanks for the content!

In my opinion the hot air intakes on that car just don't make sense. At least not in that configuration. Again just my opinion. The factory engine covers are more appealing than a tiny amount of Intake noise.

Alex loved this video, though it is a pain for you to go over so many things on your V12 Twin Turbo, but the issues you are finding and addressing is a huge service for your RU-vid community. Keep it up buddy!

I have a volant cold air intake on my 02 Dodge Ram with the 5.9l engine. The intake comes with a plastic box and inside is a cone filter with a plastic tube that goes to the throttle body. I removed the box to expose the filter and i notice that the air temp was higher and heated up faster without the box. The air temp lowered way slower once the truck started moving and cruising. The cold air box kept the air temps from rising quickly in traffic and once the truck was moving, the air temps lowered quickly. I know how you feel Alex. If something isn't working on my vehicles, it feels cheap and junky to me. Even if it's a light bulb out. If it came working from the factory, i want it to work. That's a cool letter from the previous owner. I hope to make a book to leave with my car.

Can’t wait to see what this beast does on the dyno. I have a 2007 CL600 bone stock and it absolutely destroys challengers and mustangs, i can’t imagine what this car will do. Awesome vid as always man

Would love to have a CL65, but those issues are crazy. I still wouldn’t have changed the suspension. However, it often makes me wonder why they don’t just do what Lexus does to make them last.

Alex, Thanks for keeping the promise of the diagnostic for the suspension!! I enjoy your good humor and brilliant repair work.

Ur brave man with the ABC suspension. I would see them fixed one day then back in a few days after. It was common for customers to abandon these cars at the dealership too since the repair was ridiculously high. It was weird to witness

Watching you deal with this suspension makes me so glad we didn’t buy our car with adaptive suspension since we plan on keeping it a long time. That looks so rough.

So glad to see more content on the mighty Mercedes V12. I look forward to seeing the dyno results

I was looking at creating an airbox for the kn filter on my turbo frs. It is a very similar setup as the one on your trans am. But as you mentioned you better have a hot air intake rather than restriction in air flow. That is what was going to happen with the new box. This video saved me time fabricating something I don’t really need as the intercooler is big enough. Thanks Alex

Many Thanks for the investigations to find original fault of the ABC system. You're a top notch AMG technician, it's of course your call but I'd really enjoy more videos with you working on AMG cars. 🙂

Always look forward to watching your wonderful content. For the door repair, wouldn't it better to have the solder joint inside of the vehicle and door? The solder joint wont flex like the wire. As we saw from the previous repair the failure was at the joint. Of course, it's a lot more work to take the door and under dash panels off. For a longer lasting repair consider replacing the wire with the same gauge, but a higher strand count making it more flexible.

Ohhhhh that is so satisfying seeing someone else other then me solder wiring!!! Thank you sooooo much!!

I love this beast!!!! It can’t wait to see it all done and clean, and i just know you’re going to make it sound amazing with a custom exhaust

Something similar You can get in EU Citroen C5 "Hydroactive" but it's not that easy to break. My family owns a ~2007 Citroen C5 wagon, with 2.0 turbo diesel, with Hydroactive+ (additional functions like anti-roll while sport mode on), still works fine, no leaks, no worn spheres. And diesel is 1.33USD/Liter (1 gallon = ~3.78 liters) Petrol (95, basic) is 1.32USD/Liter Greetings from Poland!

Love your videos

I'm not sure if anyone else has mentioned this, but if you go on Amazon, they have soldering heat shrink connectors, all in one. They are pretty cool, you just heat em up, and they solder and seal all in one

Mad respect for following through on opening up that accumulator...I was very interested and looks like it was a bit of a sketchy operation but thanks for pulling through for us!

Man I love that car… with you owning it and fixing it lol

Not sure I like the trade-off of the new warm air intakes over the cold air-fed factory units. Will be interesting to see if there is really much difference in power output. aesthetically, the engine looks unfinished without the covers though you might gain some cooling benefit to them being off. Really enjoy your channel. Well done!

My CL500 of the same vintage had exactly the same electrical issues on the drivers door wiring loom between the door at the A pillar starting to give up the ghost, very very common issue. Not too bad a fix :-). Glad you kept the ABC, amazing system! Thinking of getting another CL500 or 55 as they are just lovely cars (when working!) to sit alongside my 2010 XKR :-)

Thanks for all the content brother. Keep that RU-vid grind up. ⬆️ 💯

Here in Sweden the fuel price (for diesel) is 21.76kr/litre. So in dollars its around 8,8usd/gallon 💸

Very ugly with that aftermarket intake. Love the original AMG setup.

I love this channel. I've been driving my kids in a 400 dollar 2003 e320 for 2 years thanks to your videos. Lots of info and most importantly your honest approach to repairs/mods make these cars less overwhelming to own and maintain.

Always great to see more videos on this car! Been watching since you bought it from Hoovie, and she's come quite a long way! Honestly, I'm not a fan of the new intakes, but at least they're a bolt-on deal that's 100% reverse-able. Would love to see dyno numbers to see if there's actually a performance improvement or not with the new intakes. I'm sure they'd be fine as long as the filters are maintained, hot air or not. Not saying your cars are like this, but every used car I've run across that has those K&N cone style filters installed, more often than not the owner says "what do you mean they need to be oiled?" That's why I prefer just sticking with stock intake boxes unless there's a significant performance increase.

Im sure the previous owner would be very happy to see the car being taken care of!

just not a fan of this intake. Under the hood the car loses all its appeal. It looks like a civic turbo budget build.

Again a really awesome and entertaining video with some really interesting stuff that I learned a lot from once more! Thanks for sharing, Alex 👍👏🏻👏🏻😀

My 1JZ has twin intakes with pods coming from each turbo (highflowed) and makes 550whp. Yeah, it could be sheilded (and I have one that needs some modification), but your explanation about having a good intercooler setup makes perfect sense Alex.

Love the CL65 sir. What I don't understand is why you don't use flare wrenches on these fittings? Just an observation. A guy with all of your years of "mechaniking" should have all of the right tools, one would think.

12:03 FJB!!

Hey Alex thanks for the great content! For a new video idea could you go over dynamic seat faults and common repairs

So glad to see this Project completed!

Just a thought with the ABC system.. So...When you make threaded seal connections for extreme high vacuum applications, I use a simple .10 cent ACE hardware copper crush washer inbetween the metal to metal connections.. It's all the same and I understand Mercedes engineers are amazing, just look at the new EOS 580s, but could the problem be solved with a simple solution, that Mercedes did not do so they would get service money on their inovative yet shit ABC system?? Just saying!! Plus I feel the intake system you added looks and kinna is jenkie. Let it be what it is cold air boxes, with a beautiful engine cover. Also look at Bentley GT accumulators they may work better. Thanks for chopping it at the risk of your hand

15:32 PCV tube, not secondary air injection tube - that's on the other side of the engine (and doesn't go into the intake!) Great update as always.

I could see the difference in the compression fitting very well Alex, great shots! I feel like it would be really cool to do a hellcat style halo direct air intake to the turbos on this CL, or you could almost delete both the inner lights for intakes! I don't know if I'd sacrifice the clean look for the minimal and kinda odd noise it makes personally.

I do trailer repairs and service, and hitch installs, at my work, and we always do solder and shrink for all our wiring. Much more reliable and durable. I would also have suggested you put had put the canister in a bench vise, and then use an angle grinder to cut it open. Much safer, and less chance of it binding and pulling your hand into the saw 👍

Great job on this awesome car. Not a fan of that intake, looks cheap.

Those intakes are hideous

Something to remember on the piping of the intake. One 90* elbow is equivalent to 5’-0” of pipe run. So, with the old setup every bend and angle of pipe actually = a significant amount of piping length under the hood. I don’t know if I phrased this right for everyone to understand but I’d say you removed the equivalent to 20’ - 30’ of piping.

Is it my birthday? Legit CL65 V12 goodness AND M539 V12 smoothness... And no one at home to bother me.

I get your point completely about the ABC it’s a beautiful system and the only people that put it on normal coils are the ones that or aren’t good enough mechanic’s or are cheap and don’t have the money to afford actually driving these cars. Driving and maintaining these cars especially these older ABC cars just costs a lot of money. Not a fan of the filters these will help heat soak the inlet temperature fast and when older they are often very bad actually filtering the inlet air of any pollution like sand and salt.

Pulling out the torch for the heat shrink tubing is the realest thing I’ve ever seen

I was just checking out the performance of this car from accelerationtimes. The performance 0-200 km/h is 12.8 seconds and it's almost equal to Porsche 997 Turbo. Everybody knows that 911 Turbo is synonymous to "superfast" so CL65 is seriously fast car and in my opinion one of the most fascinating old super coupes on the market. There's just something that I can't put my finger on... it's just SO cool how it just goes like a jet. You won't even notice and you have absolutely sick numbers on the speedometer. The acceleration to 100 km/h to 200 km/h is STILL pretty damn fast, even by modern standards. It's crazy how fast it was almost 20 years ago. Cheers... and keep up the good work. I've been really enjoying this CL65 series.

That is a humongous HOT air intake you have installed. I bet you lose HP once that engine bay is heat soaked

Alex, you can't imagine how much I admire the matter-of-fact presentation, you make repairing these cars even a die hard car guy would walk away from. And this car really is a knock-out!! We already know how much this beast tried to beat you up!!! LoL.....Congratulations! Great work. Terrific series..

Alex, PLEASE TURN UP THE VOLUME FOR VIDEO. I have to have my TV up pretty loud for your videos and then I get SUPER LOUD ads. But what did you want to say? You wanted to re-buy the entire ABC system. Wow, yeah, that’s a big difference on the lines. The ABC system is amazing and I applaud you for keeping it!

Everytime I get the itch to buy an ABC car I watch one of these vids and I'm instantly cured lol. Thanks for sharing 👍

YES!!!BEEN WAITING FOR THIS!!!!

I agree with the so called cold air intake with a good inter cooler but with natural aspirated not so much unless the box that holds the filter is closed type. Thank you for you content and keep up the awesome work. As always be safe 👍

Yes!!! More Merc V12 videos. I own a 2005 SL65 and love getting to see what makes these cars so great, and a pain in the ass.

As a benz specialist, I find the abc system is amazing . The problem is when the cars get older and their value drops people fail to remember the complexity and how advanced this system was when the car was released. Unfortunately due to the complexity of the system the parts are still very expensive 😕. Just wait till a turbo goes bad 👎 and it's 10k to fix. You have to make sure that you oil these types of air filters or you will dust your turbos and engine Don't put a solder joint in the door jamb(basic wiring). Follow the wire to inside the car and join there. Solder the other end inside the door. This break is completely normal for the drivers door after opening and closing for a long time , not a merceces fault. The intake won't make much if any difference without ecu tuning mate. Look at what BRABUS do to their mods. The only reason the wheels are spinning and smoking is because you put the car in dyno mode which turns the esp off . This is not what your viewer's should expect in normal mode. Any benz will do this in dyno mode

Love the channel and the content….had me hooked with the lightnin’

For that little bit of whisper I wouldn't sacrifice that nice cover with the signature of the worker who assembled the motor.

Love this vid ... look forward to see more of this car

Love all the updates on this v12 beast! You just don't let anything discourage you. Love it!

Another video packed with information that gets me thinking... My thoughts and opinions on CAI... the straighter the path to the intake valve, the better. We want the lowest appreciable pressure drop, i.e. the least energy required to get air through the intake system possible. I havent taken a fluid dynamics course, but I know a few concepts... the velocity of the fluid loses its uniformity in a bend, and contributes to a pressure drop across the bend. Any tube will have some appreciable pressure drop across it, but the longer the tube and the more bends, the greater the pressure drop, especially in high flow situations. Large radius bends should be used if bends are needed at all. The thermal expansion is a factor, and it's inversely proportional to the number of oxygen molecules in the cylinder, but there are many factors which dominate that equation more than the thermal effect. (Air loses less than 10% of its density between 100F and 200F, for reference) To make my point: I think if we make an intake like the Caprice has, where the path is straight, fairly short, open to the environment, AND can take advantage of ram-effect, there would be appreciable gain to changing the intake piping. But, to do all those things for a conventional intake, especially if the throttle body doesn't face the front of the car, it will take some serious design work and it makes more sense to spend that money on a tune or cams, something with real, proven benefit for a few hundred $$$. If you are developing a race car and chasing that last 2-3% horsepower gain, it might be worth it. I know it would be easy to ruin the cone shape, but I wonder how viable sanding down and reprofiling the flare fitting would be... You would have to set up a jig to get an even cone shape, otherwise it would likely leak worse even if it were smooth! I pay $3.50 a gallon for 91 in Manhattan KS! Im glad my SVT Focus only requires 91, we dont even have 93 here... $4.70 a gal is crazy!!!

This is by far one of my favorite series!

Can’t wait to see what it does on the dyno and the track!

Nice video. Nice job with the ABC leak and the wiring issue.

My air strut went out on my E55 a few months ago and I went with the BC Racing adjustable coilover kit and couldn’t be happier!

Alex, I had the same thing on my 55 with the leak in those metal joints. You can use teflon plumber tape around that area around the threads and retighten it and it should keep the area from leaking. Otherwise those pipes go to the front of the engine or valve block and lots of labor to change. FYI coils suck, the car is designed for abc

Now that was a great way to open. Seriously good instruction.

Before kids arrived I owned an alfa romeo which I absolutely adored. Makes me well qualified to understand why you still love the ABC on this car!

Awesome vid! I see youre climbing in subscribers. I cant wait to see you at 1 million. You deserve it, youre content never disappoints.

It’s funny seeing your testing road is where I used to test out my cars lol

A very sympathic guy with an positive attitude, i like him and his way solving issues

I paid 3.65 this morning at the Costco on Touhy. That was for regular though, pretty sure my Ford Escape doesn’t need the fancy stuff. 🤣

Thank you for the sharing of inside of the 'gerenade". I owned 4 m275 & abc cars and it is 1st. time that this parts is leaking. Besides the track and ultra high speed cornering, the ABC is Absolute ultimate Suspension System, Period. Whem you ride abc, it doesn't feel so good maybe, but after that you ride car without abc, you can feel how amazing the abc was. For that intakes, I think the m275 is too mush sensitive for those modifications. Just a proper chip will give you more light start and endless power for all rpms.

We had the same problem with my daughter's 07 E Class, it was in the trunk though turns out to be a common fault the brown earth wire is the main culprit most of the time.

I had a CL600 with the ABC, when it started going bad I did a coil over swap. It never drove the same. The ABC is perfectly tuned for the weight of these cars (when it works)

Again a great video Alex! Here in Denmark, I fuel my car with petrol oktan 100, $9 pr. gallon. And oktan100 Diesel for my MB C220d, is roughly $8 pr gallon. 😅 But really loving that V12! 😍

I have a CL500 and when I had issues with my door functions and other electrical things, I replaced the SAM module and that fixed everything

Hi LSC, I love your videos and quality of editing is sublime. I think your shop would be even better with some (or maybe a lot) accoustic panels. 👍👍👍💪🏼💪🏼💪🏼

Another great video, glad you decided to keep the ABC, so many people go with coilovers it spoils the ride. I still have ABC on my CL55 and SL55

There are ways to retrofit other suspension systems onto that car, that are not only easier but cheaper. And not junk steel coils.

Really nice video as always. That thing is gonna be a menace when its tuned.

You have slowly become my favorite channel. Been watching for 2 years or so, the firebird one

Would be an option to add water jets to the intercooler locations. Food for thought

Cool Alex. Keep the humor going. Part repair, part stand up comic. Both go together well.
