Its sounds nromal as long as the lid closes tight so it doesnt come open

 

noticed the car revs fast, like if im just sittin there and pop the throttle the rpms come up faster, its nice...

 

Does anyone know if the Blue Powershot filter and cleaner kit is close enough to the SLP Blackwing filter and cleaning kit that I could use the powershot cleaning kit on the Blackwing filter(it's blue too)?? I'd order a cleaning kit from SLP but they won't do orders below $25 and I really fdon't want anything else from them right now and don't really want two cleaning kits.

 

The powershot fits better and seems to have better gauze and less light passing through than the K&N therefore likely better filtering.

NOTE TO EVERYONE: If you get any movement, especially at the rear of the filter by the neck of the lid you are letting dirty air into your engine. I have had no issue using a thing strip of weatherstripping on the "bottem" edge of the filter where the movement is.
