Great product and cheap in price.
Definitely worth the money. It is a real K&N air filter. Works Great. Way cheaper than buying it in the stores.

Versatile filter
I purchased this for a 2006 Suzuki Hayabusa, perfect fit and it got me back on the road!!

Awesome product at a awesome price!
The filter is far and away better than the OEM piece I removed. The fit and quality are top notch as well as the included instructions! My bike sounds somewhat smoother at idle and I can't wait to try out any performance gains it might also give!

Easy peasy install
Have a 2000 Hayabusa that had a stock paper airlifter on for 50000+ miles. Installed this new KN high flow and i notices a tad bit of performance increase and better air flow getting to the engine, Also my temp gauge does seem to be lower than usual on regular riding. (I ride my busa daily, SoCal weather). Install took less than 10 minutes, remove the bolts on top and done, comes with instructions too.

Fit my 2004 hayabusa perfectly
Good filter. Fit good. Only thing I am a little sad about is it came with a foam gasket that sits on the air box. Just feel like that could have been built a little bit better. Don’t effect anything with the filter just personal preference.

Best bang for the buck!
Does exactly what it’s designed to do. There are some filters like sprint for example that may squeeze a little extra power after a tune but come at twice the cost. The K&N filter is an excellent value!
