4bhp more since I fitted K&N, plus jetting. First class product.

My experience with K&N was a real pleasure. The product was exactly as described, and it fit perfectly. I was at Raceway Park a few weeks ago and asked the rep there for a direct replacement for my AF-212 air filter. I looked myself prior to speaking to the rep and the dimensions of the K&N were NOT the same as the AF-212, even though they gave me a direct replacement number. I even looked at complete kits, but your kit did not offer a drop down bottom plate low enough. My existing filter drops down 2. Any help in this matter would be greatly appreciated.I was thinking of a K&N for my Nova as well. Thank You.

Awesome.... Great fit and easy to install. After putting these filters (RC-1820) on my SuzukiSs83 VS1400 and after a re-jetted carburetor, my bike pulls harder than ever, picking the front tire of the ground with ease. Amazing what a filter can do. Thank you K&N.
