Turbosmart BMW 135i/335i/535i/Z4 w/ N54 Twin Turbo 3.0L Kompact Plumb Back Kit

The Turbosmart Kompact Plumb Back Kit replaces factory diverter valves on BMW N54 twin turbo 3.0L engines in 135i, 335i, 535i and Z4 models. It recirculates excess boost safely back into the intake pipe to prevent compressor surge and protect turbos during shifts. Built for high boost applications, this kit delivers consistent performance and reliability on tuned or stock setups.

Key Features

  • Twin Port Design: Manages boost discharge from both N54 turbos independently for precise control and no lag
  • Billet 6061 Aluminum Body: Lightweight at 1.32 lbs with anodized finish for corrosion resistance and long-term durability
  • Plumb Back Venting: Returns air to intake pipe silently without atmospheric noise or oil residue in intercooler
  • Direct Bolt-On Fit: Includes brackets, hoses and fittings for plug-and-play install on all listed N54 models
  • Adjustable Spring Preload: Three spring options included to match boost levels from stock to 30+ PSI

Product Notes

  • Requires removal of factory diverter valves during installation
  • Pair with upgraded intake pipes for best results on high boost setups
  • Ships in protective foam packaging to prevent damage

Installation Notes

  • Professional installation recommended.
  • Disconnect battery and depressurize system before starting
  • All necessary hardware and O-rings included for OEM-like mounting
