Trüpower Subaru WRX Levorg FA20 Turbo Air Inlets allow your FA20 DIT turbo charged engine to breathe the way it was meant to breathe. Vehicle manufacturers use restrictive, plastic pipes that are prone to fail and choke your engine. Factory charge pipes are thinner in diameter which also restricts air flow. Trüpower Subaru WRX Levorg Turbo Air Inlets use 3” T6061 high grade aluminum piping to ensure increased air flow. Smooth, unrestricted air flow will improve engine performance, improve engine and fuel efficiency, increase throttle response for faster acceleration and maximize power output of your FA20 turbo engine.
