Just a question....
On the S85 V10s, there were charcoal filters on the outward side of the air filter. It is there for emissions reasons....after you turn off the car, these charcoal filters are supposed to filter out the hydrocarbon evaporants to allow the M5 / M6 to pass closed room emissions tests.
Is there such a filter for the M3?
The reason why I ask is that removing these filters gave 10-15 rwhp to the M5 / M6. This is the universal mod to do and it is free.
Anyone with a new M3....can you check and maybe take some photos?
