Optimized Performance Filter for KN 303 Motorcycle Powersports Review

Overall the only reason I bought this filter is the nut welded on the top . This makes removing my 2013 Kawasaki ZX6R MUCH easier than the factory filter. They aren't cheap either. Be careful with them though, if you don't have the exact size to remove them, the nut will end up being rounded and it will be very difficult to remove. It also seems to filter well (which is probably the most important aspect of it). I would definitely recommend it to anyone who wants a smoother oil change.

Love these filters! I have a 2002 ZX7R2007 ZX10R2011 Vaquero 1700 and these filters work great. I love that I can put them on and tighten them up a bit with the socket.

Then, after 3000 miles, when I tried to take them off, it took some effort. I've always believed in using OEM factory filters, but now I really prefer them. I will never use any…

It hurts to remove that factory filter with a wrench. I got a small cut on my arm…

So winter is finally over and I've got one thing to think about. Gorgeous, shiny, perfectly tanned, looks great on the beach, good 2 parts, great curves. That's right, my bike. I first used one of these filters on a spring oil change last year and it seems to be working very well. Someone told me it was the "I'm better than you" brand. I suspect that this brand is reserved for more sporty bikes because I always find them to be very good at high revs. But unfortunately I ride a Kawasaki road…

⁃ Black K&N 303 fits my 2007 Kawasaki Ninja ZX14. ⁃ It said "Made in Thailand". ⁃ It comes with a protective polyethylene cap around the other/hollow end of the filter. ⁃ The description says the seal comes pre-lubricated, but I lubricated the seal with clean oil, just in case, the same Mobil 1 Racing 4T 10W-40 synthetic oil I used to change the oil. ⁃ I'm glad I bought this end nut filter. I tried to remove the OEM Kawasaki oil filter but it was very difficult for me. I tried removing the…
