Manufactured by Phoenix Racing the N54/N55 aluminum replacement chargepipe is a great low cost upgrade option. The throttle body flange is CNC machined and the aluminum piping powder coated black for a long lasting finish. Each pipe includes dual 1/8" NPT bungs, t-bolt clamps, and all hardware required for installation. The optional full Tial valve kit also includes vacuum line & caps to fit the Tial valve. BMS test fits each pipe on a throttle body before shipment to ensure no fitment surprises. This is simply the best value for stronger N54/N55 chargepipes out there. E chassis N54 and N55 only.
