K&N R-0990 Performance Air Filters, Norton 750-850, Triumph 152

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.
