Modifications to M3

Hi There

Can anyone tell me if adding an aftermarket induction ram air filter and swapping the exhausts will invalidate an extended BMW warranty?

Many Thanks

Hi Scott, no it doesn't.

Usually a CAI won't affect warranty, but that depends on the dealer to a certain extent. Likewise, replacing the exhaust would only invalidate the warranty on the original, which you won't be worried about anyway. If you have a regular dealer, just call them up, ask for the Service Dept and get them to check with the senior techy. Normally they don't have an issue with it unless they're a particularly fussy dealer in which case you just try the next one. ;)
