I own a 2006 C55 AMG in dimond black, it's a great car...Come here to hopefully get as much info as possible on how to take care of my car etc... so if you have any tips etc please feel free to share with me..
My car is stock right now but I'm after a CB renntech airbox, if anybody has one for sale please let me know, thank you.

Welcome aboard.
I'm aware that they are very hard to come by, I’d be right in there as soon as one becomes on available
I'm thinking of a couple of performance modifications to take the car up to 400+bhp and I thought about a ECU remap and a Renntech box would do the trick?
thanks for the welcome btw.

Wawy; I see you have few modifications on your 55, including a Renntech CB air box, is it worth spending 600-800 on one? did you see any difference? your c55 sounds great btw.
I thought it will work well with the ECU remap, well atleast that's what I have been told…
No more than a KN!!
A tune for the C55 will do nothing or next to nothing as well. Better off to just change the plugs, maybe a res delete and true dual exhaust, put K&N in there and call it a day. Unless you want to go with a Kleemann SC, there's very little mods one can do to the C55 that'll make much of a difference for the money.

How about Kleemann headers + ECU re-map and maybe if am lucky a Renntech air box surely that will make a noticeable difference…
A tune alone on a c55 will see around 20bhp, 24ibft torque and sharpens up the throttle etc..
Thanks,
Joe.

OP, true dual exhaust is surely where it's at. if emissions isn't a problem, i'd go with LT headers, secondary cat delete, and a res delete...and the K&N filters

..here you will find two other C55 owners that have tested the Renntech airbox and have shown RWHP gains. You'll notice the airbox is bigger than stock and different on the inside. My testing was done with the stock ECU. I would suspect that with a tune with a map for the airbox the results would be even better. I agree that the the "best" mod for this engine is a supercharger, however, not everyone wants to go this route (either because of cost, reliability or other reasons).

** Bad link ***
Bottom link didnt work (Renntech airbox dyno)I found this original post from AMS and WAWY:

At least it made dynoed gains so that's a good thing. How much is the airbox (if you don't mind me asking)?
Yes you could say that! If I remember correctly they are about $1250-1500 brand new for the M113 V8.

I'm not so sure about K&N had them on my c32 and my previous slk55 and the on both I had maf issues, I took them out after 7K miles and fitted the stock AMG ones back in.
or maybe go with a dry filter from AFE. http://afepower.com/

Thank you for the link buddy, very interesting, if you ever want to sell your Renntech box, please drop me a PM

As a side note, even Kleemann, who's done a ton of 113 engines keeps the stock airboxes on the C55 when they do a SC package with headers. That's gotta tell you something.

Newzchspy - fair point about the Kleemann SC mod, i'll soon get the car's ECU custom mapped and see how many bhp I can gain...
I have been offered Kleemann headers recently that combined with the ECU re-map should give reasonable gains... (I hope)
