K&N Air Filter2batt - Bristol, Wi There are some good and bad side effects "After i put this filter on my CBR600F4i i gained some decel pop, definitely more high flowing than the OEM filter, but the new filter with the PC5 for my exhaust and filter lost me 2 tenths in the quarter mile (no filter or PC5 and just a muffler was 11.52 @ 121-122 mph, woth filter and PC5 was 11.7x @ 119 mph), then i also put the Zero map on the PC5 and no change in my time or mph, i added on an auto tune and rode around for a couple days going through as much RPM and throttle positions as i could and got 11.55 @ 120 mph, each of the passes i listed had close to the same 60 foot of 1.9x while launching around 7 grand, the clutch was giving out on me after the auto tune mod since i have done a lot of passes, i will put in a clutch and see what my time will be, hopefully quicker than the OEM filter, i recommend the filter, but a real tune will be needed, cant just slap it in and expect a gain"
