K&N KA-2508 Air Filter Product Reviews

Tuesday, December 5, 2017 - Part KA-2508
Noticed more responsiveness when giving the bike gas. However, I have also noticed it running very lean due to the bike getting more air. To combat the air to fuel ratio problem, I'll either have to get it dyno tuned or buy a power comander. But other than that, the product is great. Would definitely recommend.

Quality product but wouldn't recommend for ninja 300. made no difference in power. If looking for more power out of a 300, save your money and just get a faster bike. ;)

Professionally packaged and delivered. Contained everything needed for the installation. The air filter fits the bike and improved the performances since the first minutes of riding.

Put the filter on my wife's ninja. What a difference. She loves it. With the yoshi slip on, it's fixed the fuelling with no flash. Delivery to Australia was fast and I'm very happy. Thanks guys.

A first rate service from K&N, very quick delivery, even quicker to install the air filter into my Kawasaki ninja300, which now has an even quicker throttle response and definatley more noticeable power throughout the range. Especially from mid to high rpms and a slight change in induction noise, for the better,.. The filter has instantly made the little 300 that bit more fun to ride. I also haven't noticed a drop in fuel mpg. Its around the same as usual which is surprising considering how well it runs with the filter in and added bhp ( which is noticeable ).. A great product to improve any small CC engine..
