K&N's Universal Air Filters are designed and manufactured for a wide variety of applications including racing vehicles, radio-controlled cars, generators, snowmobiles, tractors, and other applications. Regardless of the angle or offset diameter of the air intake, there is probably a K&N Universal air filter for your equipment. All filters are constructed with ultra-strong molded pliable rubber flanges which absorb vibration and allow for secure attachment and can also be stretched for up to 1/16" (1.5mm) to fit in-between sizes. K&N universal air filters are washable and reusable. When used as a replacement for the OEM air filter, modifications to the jetting may be required.

Noticed right away that car had more power. Increased fuel mileage almost two and a half mpg. I always replace the stock filter with a K&N. I have 2 Pickups and 3 cars and a Harley Davidson Street Glide all have K&N filters.

This filter designed spared me the trouble of using the Harley Davidson stock replacement kit or the expensive naked filter assembly. I have hi-flow performance concealed in the original housing. My bike is a very new production model with limited after market products available, so Thanks K&N. Harley Davidson Street 750 owner.
