BMS Elite M3/M4/M2C S55 BOV Kit

Finally, that blow-off valve sound you've been waiting for on your S55 powered BMW. Our BMS Elite S55 replacement charge pipe is made from heavy-duty aluminum and is designed with CNC flanges and a protruding lip for a secure OEM-like fit. It's finished in a gloss black powder coat to match the engine bay and includes two 1/8" NPT bungs perfect for an external boost gauge or WMI nozzle. Also includes a heavy-duty replacement coupler, O ring, C clip, and all required installation hardware.

This version features a Turbosmart Raceport valve blow-off valve to release excess pressure in the charge pipes when letting off the gas. In addition to intoxicating sound, it reduces compressor surge and improves overall reliability at higher boost levels. Includes an electronic BOV controller, MAC solenoid, and all required fittings for easy installation. Compatible with factory tuning, JB4, and flash tuning.
