V12 Renntech Carbon Fiber Air Filter For Sale
Fits V12 Bi-Turbo CL, SL and S class 2003-2011 Mercedes.
Renntech website has accurate MY and Class fitments.
I have Speedriven Intercoolers installed together with upgraded turbos, downpipes and tune on my 2005 CL65, therefore the air intake also had to be replaced.
No visible scratches.

Here is my experience regarding upgrades based on my research and driving few of those cars:
1. The tune from Speedriven or Renntech (both similar) would give you most initial HP increase for a reasonable price.
2. If you decide to take next step to replace intercoolers for bigger ones, you will not be able to keep Renntech Intake ( I have Speedriven Intercoolers and intakes).
3. One more inexpensive upgrade- downpipes.
The combination of 3 yielded 636 RWHP (high 700's crank HP) on regular fuel.
My next upgrades were bigger wheels (body work required) and upgraded factory turbos. Cannot report on the results yet. Car still at Speedriven.
Hope it helps.

Also after test fitting, the starboard side intake pipe from the intercooler rubs against the small black reservoir. How did we get around this?
