Got a Chappell slip-on exhaust a few months back and wanted a new air filter. As soon as I installed the filter I could hear a difference in the tone of the bike, so obviously there was/is a difference. Feels like I have a bit more pep to the bike too. Just about every car or truck I have owned my entire life I have put in a K&N. Always felt an improvement; great products.

Delivered on time with no problems. Fit perfectly and it definitely gives my bike a kick in acceleration and a bit more top end. Would definitely recommend this product.

I bought this for my Street 750 because I get K&N benefits which I can hide behind the original air filter cover. Super easy to fit and you still use the original housing. The bike pulls smoothly and definitely gives more performance mid to top rev range. While I have not conducted a scientific study, I find that my mpg is better as well as the bike pulling smoother and quicker. In my humble opinion, this air filter is a total no brainer. It has a pretty much lifetime guarantee, saving you the cost of the inferior filters. Provides better performance and in my view better mpg. Oh, and you can hide it behind the original filter housing.

Shipping was very quick. Didn't have to tune bike. Just replaced the stock filiter. I like that it still uses the stock cover because I park my bike outside in a parking lot. Nobody will unbolt my filiter and run away with it. Bike sounds slightly cooler. I think it runs a bit hotter, but hard to tell.

Bike performs better with this filter fitted. Breathes easier, smoother ride through all the gears, better pick up from the throttle. Glad I put it on, and of course it doesn't change the aesthetics of the bike, hidden under the original cowling.
