Boost horsepower and acceleration with the K&N Universal Clamp-On Air Filter. Featuring a 3.5-inch flange and washable cotton gauze media for lifetime engine protection.

The K&N Universal Clamp-On Air Filter is engineered to increase horsepower and torque by providing significantly higher airflow compared to traditional disposable paper filters. This high-performance oval tapered filter features a 3.5-inch (89mm) inside diameter flange, making it ideal for custom intakes and performance-tuned engines.

Constructed with multiple layers of oil-treated cotton gauze, the filter media captures harmful contaminants while maintaining low restriction. Its clamp-on design allows for a secure, airtight fit on intake tubes, while the durable rubber moldings ensure longevity under extreme under-hood temperatures. This filter is washable and reusable, designed to be the last air filter your vehicle will ever need.
