i have the drop in type K&N, didnt notice changes in performance, or mileage...but where i did find change was in my pocket! i paid about 45 usd for the filter, and here in mex, the replacement filter costs about 11 usd so every 2500km i cleaned it and if you consider it, its like buying a new paper filter, right? so i have cleaned my K&N about 10 times, 10 times a saved 11 usd, so yeah, its worth it.and it doesnt have any sign of wear or so, so itll last about 100000 km i think...
