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.

Filter works great on my stock intake replacing my oil bath air filter on my CJ2A. Jeep was running rich, but now it runs great. I was torn weather or not to stray from the stock setup, but I am glad I did. These filters are great quality and super easy to install.
