*** 55 Kompressor Air Boxes on NA V8s ***
55 Kompressor Air Boxes are best flowing air boxes that AMG makes. With some slight modifications to them they will fit C55, CLK55, CLK500, CL500, S430/500, E500, CLS500, SL500 and G500.
Car above is C55, on which the airboxes are worth 10-12 RWHP, more with other mods like headers and cams.
We offer these boxes modified, ready to bolt on, with K&N filters for - $549. We are also looking into making a cover from 63s fit upfront or we can make a custom CF cover, like the last picture.
I will post further details on the covers.

Man I wanted one! I guess I'm a bit late I already ordered the RENNtech box. I got a fair price on it.. Well at RENNtech idea of fair. But question on this box that I have is... My car Dyno'ed at 291.4 and 301tq with K&N's alone. Granted i did not do a baseline (stock filters) so saying all is kinda equal (baseline HP) I picked up 17hp give or take a bit over stock. I understand that these cars can be different from the next. IF this Car that you show the dyno numbers for already had K&N's at baseline dyno 273hp is kinda low dont you think Even for stock filters its kinda low? That's a 25% drive-line loss! Personally And I could be wrong but Ive never heard of a 25% drive-line loss on C55's maybe AWD cars but 25% drive-line loss seems high. (25% loss is based on the car has 362hp at the crank) I think most of the added flow you get from any airbox you buy is coming from high quality filters.
I'm putting the RENNtech Box to the test to see if there are any added gains there and there very well may not be any gains. I would like to see how many CFM's the E55 box flows over stock airboxes and how many CFM's the renntech box flows. All In all dealer cost for this airbox is around 600 with out filters. This box has K&N's and its cheaper. So with that said its a good deal.

On a stock airbox K&Ns are hardly worth any power, I have tested them before.
Most stock C55s that I have dynoed are in 290-300RWHP range.
If we use 17% loss, than 362 x 0.83 = 300 HP at the wheels.

On this thread says the C55 already had K&N's and base line was 273HP assuming Im reading the dyno right. and after E55 box with K&n's it was 290hp??

WOW... I wonder where you got that idea from.
Congrats on the new discovery.

WOW.. So that baseline shows about a 25% drive line loss. Is my math wrong? 25% of 362= 90.5... So 362-90.5= 271.5 and 271.5 is wheel HP? So 24-25% loss? what i dont get is i dyno'ed at 291whp on a dyno dynamics dyno with only K&N's and your dyno shows 290ish whp with E55 box and K&N's. again this is a good deal that beats the dealers price by $50 and you get filters. thats a good deal.

Wow... you guys are kidding, right?
Darker red line is original rwhp, lighter red line is original rwtq. Darker blue line is modded rwhp, lighter blue line is modded rwtq. Car started with 291 at the wheels, and ended up with 301 at the wheels, for a +10 rwhp gain.
You're reading the original rwtq line as original rwhp, and the original rwhp line as post-mod rwhp? Did you notice that doesn't make ANY sense?
Horsepower and torque ALWAYS cross at 5252 rpm.
As Mugatu once said... "Doesn't anybody notice this? I feel like I'm taking crazy pills!"

HP = (rpm × Torque) ÷ 5252
Consequently - no dyno in the world can show HP and torque NOT crossing at 5252... it isn't possible. High school (maybe grade school?) algebra here...

For the record, I can't believe Vadim's post in post #7... Vadim, you might want to re-read that (since you even quoted it) and look at the graph again before stating "correct"

Seriously what is confusing to me is on a C55 the torque is in most stock cases a larger number than HP and One would just assume whos only ran two dyno's ever (Me) would think that the red lines went with the red and blue with blue. Thats why before I asked if i was was reading it wrong. thats why it didnt make sense to me as i was thinking the baseline HP was in red and the baseline torque was in blue

If you look at the graph again, notice that the numbers (i.e. text) are only describing the hp and torque for that given rpm value (approximately 5600 rpm). They don't appear to be citing the MAX rwhp or rwtq figures for these two dyno runs... if they were, those would also be the highest "peaks" for the given values, and they're clearly not.
Blue run appears to make max rwtq of about 307 ft-lbs @ ~4200 rpm, Red run appears to make max rwtq of about 290+ @ ~4500 rpm. Blue run appears to make max rwhp of ~305 @ 5800 rpm, Red made a max of ~295+ @ 5800 rpm...

Any chassis dyno that didn't utilize atmospheric correction factors would essentially be worthless - you're never going to test under the EXACT same conditions, so without the appropriate correction factor, you'd be left with an "apples and oranges" guessing game... who wants that? What you do want is a system that's tied directly into a weather station, and doesn't allow the dyno operator to manually "tweak" the numbers to try and yield a high result. From the above link off of www.dynodynamics.com under "specifications" - it sounds like their dynos use correction factors, as they should.

I guess I should've clarified one thing I said, when I mentioned the car picked up 10 rwhp... it picked up 10 rwhp at roughly 5600 rpm.
