K&N's universal inverted dome filters are engineered to provide exceptional airflow and an increase in engine performance. They are designed and tested using computational fluid dynamics (CFD) analysis, flow-bench analysis, and dynamometer testing, and incorporate a unique inverted cone design that helps direct a high level of airflow to the throttle body. Manufactured for a wide variety of applications and unique filtration needs, K&N universal clamp-on air filters feature the same advanced technology as the K&N stock replacement filters - providing quality engine protection that you can trust. These versatile filters are washable, reusable, and durable, and are constructed with ultra-strong molded pliable rubber flanges that absorb vibration and allow for secure attachment.
