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.

Very Firm Latex Medium, Appears Well-made
Size: Standard (Medium)
I love latex pillows, used them for decades. Then I got led astray! My neck reminded me I need firm, but soft and bouncy. This pillow is surprisingly firm for a medium. So think twice before ordering firm.

Comfortable but smaller than a standard pillow.
Size: Standard (Medium)
The pillow is bit smaller than standard length wise. It takes a while for the smell to go away. Very comfortable pillow.

Remarkable and impressive pillow
Size: Standard (Medium)
The pillow came quickly and was what was expected. After 6 months of chronic neck pain, one night on this pillow has made a world of difference. Please buy one of these if you are on the fence. They are wonderful. Highly recommend.

Not any more breathable than other pillows
Size: Standard (Medium)
I got this in hopes that it would be cooler than other pillows but it seems to hold the same amount of heat. Additionally, as a side-sleeper, it is too thick for me. It is however pretty comfy and seems to be made out of quality material. As other reviews stated, it was smelly at first but that went away within a week.
