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.
