The K&N Engineering RU-3580 Universal Air Filter is designed for a broad range of applications, including racing vehicles, generators, snowmobiles, tractors, radio-controlled cars, and other equipment. Its universal design accommodates air intake systems with varying angles and offset diameters, making it a practical replacement or performance upgrade for many custom and specialty applications.

The filter features an ultra-strong, molded rubber flange that helps absorb vibration and provides a secure connection to the intake tube. The pliable flange can stretch slightly to accommodate in-between fitments, helping simplify installation when the intake diameter is not an exact standard size. The reusable filter media is washable, allowing the K&N RU-3580 to be cleaned and serviced rather than routinely replaced.

For additional protection in dusty or demanding environments, the compatible K&N 25-3900 Air Filter Foam Wrap can help shield the filter from debris. The K&N 99-5000 Filter Care Service Kit Aerosol is also available for cleaning and re-oiling maintenance. This product includes a one-year limited warranty. It is not CARB approved, and applicable emissions requirements should be reviewed before installation or use. Fitment depends on the intake configuration and application; verify the required flange and clearance before ordering.
