  1. Best High Performance Drop in Air Filter

    Intake & Exhaust
    Need help with best high performance drop in air filter for 2012 R/T 6sd manual with Super Track Pack. First are they really any better than stock OEM? Since box is already set up "cold air", do you need to do new box or just get different filter? Best brand (Mopar / K&N, ???? etc. etc. ??? [email protected]!)...
