aFe Power BladeRunner Charge Pipe Upgrade - F3X 335i/435i (Automatic Transmission)

On turbocharged motors, the intake piping is put under constant pressure while the engine is running, and has to hold that pressure without leaking. Unfortunately the smallest amount of damage or defect on the intake hoses and the pressure can cause a leak, leaving you without proper boost pressure.  Replace your leaking pressure pipe and stop loosing boost.
