K&N Universal Clamp-On Air Filter - 3in Flange, 3.5in Base/Top, 5.75in Height

This K&N Universal Clamp-On Air Filter is engineered to increase horsepower and acceleration by providing high-flow air filtration with minimal restriction. Designed for custom intake systems or as a performance upgrade for existing filters, it utilizes K&N’s signature oiled cotton gauze media. This multi-layered material captures contaminants while maintaining superior airflow, and unlike disposable paper filters, it is fully washable and reusable for the life of your vehicle.

The straight cylindrical design ensures consistent surface area for intake, making it an ideal choice for forced induction setups or tight engine bays where a tapered filter might not fit. The filter arrives pre-oiled and includes a heavy-duty stainless steel worm gear clamp for a secure, vibration-resistant mount to any 3-inch intake pipe or flange.
