sicne i dont have 4 g's for the renntech airbox anyone have any suggestions? heh

 

These dont give you any HP gains at all, its just like have the stock intakes... i would suggest you stick with stock, but here are some examples of cone filters...

CLK430


S500


What most CLK500 and E500 owners are doing, is swapping the stock right air intake for the intake from the S500 because it is less restrictive, see if you right intake has a huge dent in it, if it does, its restricting the flow, but Im not sure how the AMG engines look, this just information from the 500's.
Here's the difference in intakes... they are about 10 bucks for a replacement.

Becareful, sometimes you can get malfunction errors etc when doing modifications like this, thats why I wouldnt advise anyone to stick cone filters in their engines, they are practically useless.

 

I have built and tested many different systems. I did not dyno, but tested the 0-60 and 1/4 mile times.

The best results came from moving the MAF sensor to the front frame rail and putting the air cleaner under the front bumper.

You could have a heat shield made in the front fender well, but I wanted maximum results.

The throttle response was better as well. I used 3" Aluminum to build the system when my car was N/A.

You can use 3" silicone elbows and connectors and a 3" K&N. If the throttle body is the same as the 01, then a 3" elbow will fit there.

You just have to have a breather bung welded in to go to the valve cover.

All in all it was a consistent .1 to .2 tenths improvement.

I still can not believe how hot that air is in the air box.

I remember it was about 25-30 degrees hotter than the system we built.

 

BTW, I would guess the setups in the pictures would lose HP.

They are sucking in all of the hot air from the engine compartment.

They are basically hot air intake systems.

 

hahahaha LOL They pwned themselves good!

 

yea, arent intakes supposed to have heat shields??

 

Those intakes are useless, they only look good, besides that they are just causing more problems and losses in performance...

 

There's a Renntech airbox on e-bay right now (from a CLK60)....do a search.

 

he says the renntech airbox only adds 13hp. How is this possible if the clk55 airbox supposedly adds 20. Something doesn't add up. Renntech's site claims 23 w/chip and intake, chip alone adds 10hp so intake only adds 13hp?!?!??! Either someone is bsing about the clk55 intake adding 20hp or renntech underestimates their product ALOT! He wants too much for it anyway.

 

Nobody had dynoed the CLK55 airbox compared to the CLK430 airbox. When I asked the responses were it just did.

I do not believe 20hp.

That is saying that out of the 68hp difference between the CLK55 and CLK430, about 20hp comes from the airbox?

I would estimate 5-13 hp for any good cold intake system. Those are real numbers.

Again, the throttle response was my big difference.

 

I've considered it, being that it's the least expensive engine mod for the CLK55, but I'm concerned about what will happen if I eventually go with a supercharger. I'm sure that they won't be compatible...

An interesting point about the Renntech airbox/ecu imho. I read that the airbox/ecu raises peak torque by 26 lb/ft to a peak of 402 lb/ft, which I think is pretty respectable. I also noticed that the peak torque is lowered to 3000 rpm versus 4000 rpm with the stocker. I'm curious as to how much torque the stock engine makes at 3000 rpm, being that there's surely even more than a 26 lb/ft gain at that engine speed with the Renntech mod. If the stock engine makes, let's say 15 less lb/ft at 3000 rpm, then you're looking at an actual 41 lb/ft gain!! That would definitely be a noticeable difference. I think it's also convienent that the CLK55 is doing just under 80 mph at 3000 rpm, which is my "average" speed on the interstate. I guess I'm just going to have to think on it for awhile...

p.s.) Renntech is owned/operated by Hartmut Feyhl, who used to be AMG's technology director for some years, so I have alot of faith in Renntech products...

 

Correct me if I am wrong, but the two airboxes between the 500 and 55 look identical to me. I was under the impression that the power gains of the 55 were solely from the displacement gains and different cams. The intake and exhaust manifolds are the same, I know that much for a fact*, so I can only imagine that the airbox is the same as well...

* I had my local parts guy compare the parts #'s between the CLK500's intake and exhaust manifolds to the 55's. They were the same number...

 

I'm talking about the w208 clk430 vs. w208 clk55 because someone had posted that there was an airfilter housing on ebay (for a w208). Sorry for any confusion. Anybody have any dyno numbers to prove the gain? If you do, I'll buy one tomorrow.

 

As far as a dyno sheet for the Renntech mods, I'd really like to see one as well, especially a "Before & after" run. I'm especially curious as to what and where the biggest torque gains can be found with the Renntech mod...


Best regards,
Matt

 

I was referring to the clk55 airbox vs. clk430 but renntech dyno would be nice too.

 

If anyone is interested in the renntech clk airbox i know someone that's selling it for 1250. E-mail me if you're serious.

 

you can buy the renntech carbon box for $1500-$1800 by itself,using airbox by itself added enough performance to be noticeable in day to day driving,but under accelleration it pulls noticeably harder,these results came after car had already been chipped
