Renntech AirBox
Read a bunch of threads about Renntech's CF airbox. Was wondering if anyone can provide a first hand account if the airbox upgrade is worth it. Was looking at the following: http://www.renntechmercedes.com/www/node/56
Can anyone verify if you actually get any HP gains and are there any downsides whatsoever in installing this airbox on a CL55?
I know it's expensive, but money aside, I want to hear from other members who have installed this and what their experience has been and if there is any concerns I should have with installing it?

I dyno tested both ways (stock VS ren CF box) and could not find any HP gains. Box looks nice and fit well, but still uses the same stock size filters. It does smooth some air flow out in the neck area but again, seems like stock size filters are the real bottle neck.

Is it common knowledge and does everyone agree that the Rennetch airbox, regardless of the size does not increase HP?
