Modbargains is proud to introduce the newest diverter valve for the N54 engine, the Turbosmart Kompact Plumb Back Diverter Valve. The Turbosmart Plumb Back diverter valve is different then other diverter valves in that it is specifically designed for the N54 engine, where others are simply designed for a multitude of applications. Most importantly this diverter valve replaces your factory plastic bypass valves for an easy, 100% bolt on installation. This is an ideal upgrade for anyone who is running higher boost (software or tune) and a necessity if you would like greater boost response and no boost leaks.
Does NOT FIT 535i.
Please note - This is a diverter valve, and is designed to keep your N54 stock sounding, and will not produce that ""woosh"" blow off valve sound. If you are looking for the Turbosmart Kompact Dual Port Blow Off Valve click here.
