BMS BMW/Supra B58TU Gen2 Charge Pipe Blow-Off Valve (BOV) Kit

BMS Elite B58TU Charge Pipe Blow-Off Valve (BOV) Kit

Finally, that blow-off valve sound you’ve been waiting for on your B58TU powered BMW or Supra. Designed and manufactured by Burger Motorsports in the USA. The BMS Elite is the highest quality B58TU charge pipe upgrade on the market. Our charge pipe is constructed from high-gauge aluminum featuring a CNC throttle body and turbo flange for a snug, OEM-style fit. It is completed with a matte black powder coat to coordinate with the engine bay and boasts three 1/8″ NPT bungs ideal for an external boost gauge or methanol nozzles. Its double o-ring seal design on the chargepipe flange that attaches to the turbo is designed to withstand up to 40+psi of high boost. In comparison, other makers reuse the single OEM o-ring, which is not suitable for high boost.

Also includes a heavy-duty replacement coupler, o-ring, c-clip, and all required installation hardware.

This version features the 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. Compatible with factory tuning, JB4, and flash tuning.
