Our BMS B58 Gen 2 (B58TU) charge pipe upgrade is constructed from high-gauge aluminum and features a CNC throttle body and turbo flange for a snug, OEM-style fit. It is completed with a black finish 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-rings, clamps, and all required installation hardware.
