I have not had good experience with K+N "wet" filters in the past as they can be variable over time, even after washing and oiling, the idea of "re-using" a particle filter doesn't make logical sense to me...the filter will never be as effective after the 1st wash and oil...
many would disagree with the above no doubt.
Has any st1300 member felt a significant improvement in performance or milage (or lack of milage..) with swap over from OEM to K&N??
I'm running a K&N and any improvement in performance or economy is in the advertising. They claim to "breathe freer" but logically that should reduce filtration efficiency.
I bought one to save money and save chasing the right filter every oil change. The cloned oil filters are readily available, less so the air filters.
Over 126 refuels pre-K&N my average l/100 km was 5.4793.
Over 42 refuels since, the average has been 5.3809 l/100 km.
To me, that's not statistically significant, but at least it's not worse!
