Engine Air Filter: High Performance, Powersport Air Filter, KA-6512

This fits Perfect in my 14 ninja 650ex, feels durable, comes pre lubed, fits snug, easy to install, packaged nice. Im Happy with the overall quality! Thank you and hope this helps. Safe riding

Installed on 2016 Kawasaki Ninja 650....completely changed the air flow of the bike. It definitely gave it a little more power, and I can definitely hear the lower rumble of the engine. I highly recommend that you go ahead and put the money into this bike

I used the washable filter for my old 2009 Ninja 250, so I purchased this one for my 2012 Ninja 650 (Er6F). The included instructions were simple, and the installation was easy (after removing seats, fuel tank, and air box). I noticed an immediate difference in air intake, and my ride breaths better (probably increasing performance). I recommend it!

Second K&N filter for me/ As expected, you can hear the engine breath better. More intake noise and rasp. The seat of the pants power gains feel negligible. Since this went in with a servicing, we'll see if there is any difference outside of the "fresh bike" feel. Why not get a high performance filter for your high performance machine?

Took a minute to install on my 2015 ninja 650. Needed to completely take off gas tank. That was the most difficult part. Other than that, it was pretty straight forward. On my first ride with this filter, I immediately noticed a power gain in low end. When ever I took off from a stop light, I could feel that the front wheel was wanting to lift.

Nice filter

Perfect fit, great instructions. Maybe it was the rest of my tune-up, but my bike spins first gear now and roll-throttle wheelies in 2nd.

Excellent Filter

Super mais pour l'augmentation de la puissance, il faut mettre un power commander du genre DYNOJET, sinon cela ne servira à rien du tout, aucun changement par rapport à celui d'origine si ce n'est que j'ai perdu 3km/h en vitesse de pointe, et niveau accélération aucun changement je roule en er6n injection en full avec ligne titane ouverte, mais avec un power commander, le vrai, alors la ça change tout !

It's a K&N air filter - it works as described and you will notice gains in fuel mileage. Just remember - if you have an exhaust set up - you need to calibrate your computer (ECU) in the car to adjust for the increased airflow. Need to dyno or tune your own ECU for proper air/fuel mixture - otherwise your engine is going to run "HOT"

Excellent Performance.. has boosted the engine performance by atleast 1.5x - one can feel the significant change once the air filter is installed. The packaging was very well done and came with proper installation instructions. Took me 15 mins to change the air filter.

Passform für die Kawa war perfekt. Einfach zu verbauen. Leistungssteigerung gibt es keine (ist nur ein Mythos), dafür allerdings einen Filter, welchen man reinigen kann. Vergleich Standart vs K&N (siehe Bilder)

Embona a la perfección, no hay necesidad de modificar nada, es un poco menos pesado, y la succion de aire es muy notoria, es una pieza 100% original, agradezco al vendedor
