The K&N RG-1001BL Universal Air Filter is a performance-engineered, clamp-on solution for custom intake configurations across racing, specialty equipment, and industrial applications. This round tapered filter features distinctive blue media and a chrome top, providing high-flow filtration and a secure fit for 4-inch intake tubes.

Constructed with molded pliable rubber flanges, this filter is designed to absorb engine vibration and resist cracking. The flange material offers enough flexibility to stretch up to 1/16 of an inch (1.5mm), facilitating a tight seal on in-between pipe sizes. As with all K&N universal filters, the media is fully washable and reusable, providing a long-term alternative to disposable paper filters.
