I've been researching and can't really come across anything. I read the thread on a Renntech intake, but can't find pricing out there. Is there any intake that is top notch, and what am I looking to spend on an intake.

Thanks,

Chris

 

VRP intake! Basically it's the V8 Kompressor intake (E55, SL55) and it has been modified to fit the C55. Otherwise, you could go with the overpriced Renntech intake which is over 2K and the gain is a few more HP over the VRP!

 

??????????? The Renntech is over 2k??????????? Do you have a link, or a how to on this VRP intake

 

I think you have to call Renntech in order to know the exact price, attached is the Renntech products catalog for w203 . The VRP intake is about $500. Search the forums and you will find plenty of threads about both intakes with comparisons and dyno results as well. Good luck!

 

the VRP is just the boxes and y splitter off of an E55 or SL55 with K&N or similar filters in them. they are OEM parts available from the dealer, but your engine cover will no longer fit FYI...

 

+1 you can get an aftermarket cover that will fit I presume..incase you go this route.

 

Can you please post some links for the aftermarket covers? Here is my VRP intake with no engine cover!

 

I do abracing u get the best air flow and it cost the less

 

U can go on YouTube and look up abracing and u the vids og it on my clk500 there r 3 VIds

 

The E55 intake on the C55 makes no power. I've owned both, and dyno'ed both. the Renntech airbox makes power, and the E55 airbox does not its really that simple.

The E55 and renntech airboxes use the same stock filters as the C55 intake. The renntech airbox can hold more volume. over the stock and E55 intake.

IMO, based on countless dyno runs. There is no gain to be had with using a 55K airbox on a NA C55.

+1, plus not having an engine cover isn't very aesthetically pleasing.

 

Yeah, its funny how we were told the E55 boxes would make about 10rwhp on the N/A V8s! Sorry, I'm still a little bitter......

 

It is all about the abracing cold air and not a box

 

The C55 airbox is a real nice piece and IMO, makes the engine look nice. Not to mention it does make power. Win win in my book.

OP: search fro a used Renntech airbox. They pop up from time to time.

 

If you want a tube style intake. people should just make their own and slap a come filter on it.

If people want an tube style intake for the C55 I can get them made. its not a problem at all. Truth is though I don't know it it will make any power no matter how nice it comes out.

 

They make lots more power I had a modded stock moded rentech and then I got abracing and they have the best set up my clk500 does 13.4 in the 1/4 and that is with it b ing 87 out side and if u don't no stock is 13.9
just look on youtude seach abracing

 

The only real time you will gain power from upgrading airbox is going from a non-amg airbox, to the NA 55 Airboxes on a non AMG simply b/c the non AMG airboxes are extremely restrictive in most cases. But going from 55 to 55K on an NA car rarely shows any positive results most probably due to the law of diminishing returns. At a certain point the engine simply doesn't need any more air.

The main reason this is the case is the post air filter volume and shape of the airbox on the AMGs is larger. Renntech merely continued this trend with their CF/OEM AMG hybrid airbox and make the cavity even larger with a smoother bend at the end. Increasing airbox volume pre-filters won't really do much of anything.

Regarding tube based intakes.... They are metal (heat soak) and aesthetically unappealing. For this reason most people won't do them (regardless if they make real power or not, which has yet to be 100% confirmed). They just look ugly (no offense to anyone)

The real reason this is the case though has more to do with the overall system itself. AMGs come with amazing OEM airboxes (far superior to BMWs designs). Almost all of the restriction on these AMGs is on the exhaust side (specifically on the front half of the exhaust system which are never almost always off the shelf non-amg components with a few rare exceptions). Everything after the 2nd cats on almost all AMGs (except C36 & C32) is free flowing and provides no power advantages and therefore should never really be touched. Unless you fully unlock all of the exhausts potential (high flow headers, high flow secondaries and/or high flow primaries) then it won't make a difference what you do. With a fully modified exhaust system, software, pulleys & etc, THEN you might makes some decent gains but there is yet to be an financially viable/reasonable option for most people to upgrade the OEM AMG air boxes that comes on these AMGs (showing AMG really did their homework and tuned the airboxes for exactly what their engines needs, and then some).

Moral of the story: Just slap in some K&N filters and put a fork in this thread

Hope that helps.

 

FYI, the bottom half of the renntech airbox is from your stock airbox. They smooth out the interior and raise it about and inch then add the cf on top. When a first purchased mine they wanted my stock one for a core. I am sure they don't do that anymore but once they did.

 

what do you mean by that ? you mean the fins inside the box and they were cut it out for better flow?

Yes sir thats what I meant they took all the baffles inside the air box. This is interesting im thinking to do that too to my new car plus K&N filters. Thanks for clarification . Did you end up doing that ? smooth out the internal ...wonder what did you used to the job ?
