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.

K&N has a great web site. I used their vehicle search to find the correct filter for my Harley Davidson 103. I really like the nut on the end of the filter as it makes installation and removal easy, no special tools required. An overall excellent experience Fast shipping as well.

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.
