Welcome.
The ‘search forums’ option works for new guys, right?! :grin2:
Seriously, there’s plenty of threads on this K&N (RK-3940) as a few of us are running one. The highlights? Not much smaller than stock; slightly increased HP; greatly increased intake noise!; many people don’t rate K&N (I like mine); and, there’s smaller options out there......
Regular viewers - Did I miss anything??
