CarBahn Cold air intake consists of a Carbon Fiber Airbox Lid replacement for OEM airbox lid to reduce weight and add visual appeal to the engine bay and a high flow filter. The high flow filter increases power between 7-15hp depending on boost pressure and application. CarBahn CAI is completely sealed like the OEM system, so no power is lost from hot air leaking into the intake like most aftermarket systems that are designed for style and noise, not function.
