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.

Product Reviews


  I bought this filter for an intake fabrication project for a VW 16V motor.
K&N has an excellent fit and quality. The shape of the cone can be mounted even in limited engine compartment spaces.
I would like to see a shorter coned version if K&N decides to make one and an optional metal shield for this type of filter.
