Built for performance and show, the Typhoon? Air Intake System is a free-flowing mandrel-bent aluminum tube induction system designed to the Mazda Rx8. Each kit is proven on a rear-wheel dynamometer to increase horsepower and torque. Typhoon intakes come in the cold intake design. The Rx8 Typhoon intake comes with an oversized High-Flow conical air filter designed to provide increased surface area and dust capacity. This extra surface area provides even more airflow at lower restriction than a standard K&N O/E replacement filter that is limited to the size of the factory air box.
