The Turbosmart Kompact Plumb Back Kit is a high-performance upgrade for the factory plastic diverter and bypass valves fitted to the BMW N54 twin-turbo 3.0L (135i, 335i, 535i, Z4 and more). It replaces the plastic-and-rubber system with motorsport-proven billet aluminum valves running Turbosmart's boost-balance technology and a 28mm high-flow positive-sealing piston, recirculating boost back into the intake as a direct swap for the OEM units.
