- Rugged Construction: K&N Air Filters are manufactured with durable, premium materials and state-of-the-art construction methods to last a lifetime
- 6 Layers Of Protection: Multiple layers of premium cotton gauze treated with a specially-designed tacking agent work together to create an intricate mesh of engine filter media that is designed to block and trap harmful contaminants
