Airflow / Volumetric Efficiency

Huge, high-flow conical air filters are the first step to increased airflow to the engine. Steel heat shields or molded plastic air boxes keep hot air out and fresh, cold air flowing to the filter. Velocity stacks and precision-designed intake tubes provide smooth, uninterrupted airflow to the turbo or throttle body.
