EVO QuickFlow Air Intake System: Due to strict noise regulations, the Porsche Boxster/S is equipped with a sophisticated two-stage resonance induction system. The air intake tubes from the OEM airbox to the throttle body incorporate resonance chambers.

These "dead air" chambers impede airflow and reduce intake sound. By installing the "QuickFlow™", the OEM restrictive resonance chambers are eliminated which allows for better air flow and sport engine sound. The QuickFlow™ Induction kit utilizes the OEM airbox but replaces the restrictive plumbing to the throttle body with 2 CAD designed, cross-link plastic air intake feed tubes. Also included with this system is a K&N high-flow reusable cotton flat panel air filter, high temp silicone hose couplers/ hump hose, OEM stainless steel hose clamps and associated fitting hardware. This easy 20-minute installation improves power and sound.
