BMS BMW/Supra Gen 1 B46 B48 Charge Pipe Blow-Off Valve (BOV) Kit

Finally, that blow-off valve sound you've been waiting for on your Gen 1 B46 B48 2.0L powered BMW/Supra. The massive Turbosmart® Raceport® blow-off valve lets unused charge air to vent to the atmosphere giving off the desired "Pshhhh" blow-off sound all turbo owners love.

The BMS Elite is the highest quality B46 B48 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 textured finish to coordinate with the engine bay and boasts two 1/8" NPT bungs ideal for an external boost gauge or methanol nozzles. 

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

This version features the Turbosmart® Raceport® 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.
