Forge Motorsport BMW B58 Boost Pipes M140 M240 340i 440i

The Forge free-flowing charge pipe kit will increase flow and improve the reliability of your B58 engine from BMW. These high-quality aluminium pipes are a direct replacement and will fit in place of the OEM plastic pipe. The OEM pipe can become brittle and fail under increased boost pressure, so we have developed a replacement with an increased diameter, which helps to reduce turbulence and maximise flow into the engine.
