after i put in the K&N air filter do i have to do the 20times brake reset procedure to get the result ??

Nope. BTW, what "result"?

yeah also wonder about the "result" if you're expecting mindblowing power or something you're gonna b waiting until you buy a differnet car(one with more power/torque)

nah i was just talking about the slightly result then you probably suppose to get which is the little MPG and HP that might get

sorry to disappoint but your very unlikely to see either maybe a LITTLE more mpg but thats all

^true....the K&N may actually LOSE HP since it's sucking in HOT air from the engine bay instead of as cold as it could be!....but either way HP and MPG gain will prob not be measureable!...intakes on this car are mostly for sound/looks and that's about it since the stocker is made pretty damn good(well at lease once you do the OEM air box mod)

I think, in this case, the OP is using a drop-in filter.
