2008 CL63: whats the verdict? stock air filters or aftermarket?
Should I ...
A. just go completely stock with charcoal filter in place and new MB filters.
B. remove charcoal filter and use new MB filter
C. Remove charcoal filter and use HiFlow or K&N or someone like that?
For those of you with aftermarket, did your dealer ever say anything about it while under warranty?
