There's one thing K&N filters will get you, and that's airflow. This can get you those last couple ponies you need to catch your rival while streaking toward the finish line. Combined with the lifetime warranty (handled by going through K&N directly), you can expect to be set for the life of the bike. Fitlration lags behind OEM filters relative to the increase in airflow, so you'll want to make sure you keep an eye on your rings and cylinder walls along with your spark plug changes (something you should be doing anyway!). If you don't mind somewhat lower filtration in trade for greatly increased airflow, you're looking at a great option.
Fit my 2012 YFZ 450 perfect without modification. Performance gains seem minimal but now I never have to buy a new filter again.
The filter was a perfect fit and was extremely easy to install. I noticed a small increase in throttle response, and power. Well worth the money.
I just installed this so I haven't had to clean it yet but that idea appeals to me! Spend $80 once and it should last as long as the bike with proper cleaning and oiling.
The filter fit great and came with a few decals.
I've wanted to get one of these filters for my Yamaha R1 for awhile, and I wish now I would have gotten it sooner. I knew there'd be a little more power and a little better fuel economy, and it's definitely a notable change, but the throttle is smoother as well as engine braking. The exhaust tone is much better and has a far more tuned sound to it. One simple mod made my bike all around more enjoyable to ride!
I bought this to replace a UNI foam air filter that had deteriorated over the years to the point of crumbling at the slightest touch on my friend's Honda 50. I have a 2004 SDG mini that came with a similar filter which is still in good shape today, so I have no doubt that this filter will last and require less maintenance.
Easy to install, fit as well as the OEM filter and power is back to normal.
Adds a little power and keeps the dirt out
Install was quick and easy, shipped quickly also!
I had the prescribed 15,000 miles on my 2010 BMW S1000RR and was looking for a replacement. The K&N is priced a few dollars more than a stock paper filter but will last nearly forever..... Not a very difficult decision. Motosport.com had the best price I could find for the K&N. Product was delivered a day ahead of expectation.
Best service, best prices!!
I got this filter beacuase it was cleanable didnt expect much of a performance boost I was wrong there is a noticable improvement in power
Gas mileage increase right out the box.
Mounting instructions easy to read.
Take off side panels of the bike to aid in the installation process.
Instant increase in initial power when i lay it on her. thats where i noticed the difference to my old filter. gets the air she wants, right away
once again k&n makes me happy. bikes running smoother with better throttle response.
2001 warrior stock replacement. Get it dirty, clean and reoil. Lasts a lifetime
I bought this for my 2005 honda cbr600rr to replace the stock filter. The power difference was immediate over the stock filter. Being able to service the filter is awesome , especially with the serivce interval. In my opinion its a must have upgrade. My only complaint was needing to modify the tabs in my airbox for proper fit.
Easy to install, fit right in place with no modifications what so ever. Lifetime warranty means no more disintegrating foam type filters any more.
