K&N Filter I've head good things about...never heard of anyone having a K&N Intake
in their Celi though Injen
are both good brands. I've had an Injen Short Ram
for over a year and it's awesome
You'd have to check the K&N site for more info. ANY Intake
or performance part can void your warranty if the service dept. thinks it might have been a factor...or if they're in a bad mood.
