The Typhoon™ Air Intake System is a free-flowing mandrel-bent aluminum tube induction system designed to provide cooler, denser air to the engine for increased performance. It is a direct replacement for the restrictive OE air box and the constrictive factory air filter and inlet tract. Using the most advanced airflow management technology, K&N has optimized the flow characteristics of the Typhoon Air Intake System to complement it's high-flow Filtercharger®.
