An aluminium charge pipe kit for the B58 Gen 2 engine, as fitted to the BMW M340i and many other models. The standard charge pipe is fragile and can break even on stock cars during track sessions. do88 joins the two pipes with an aramid reinforced 3-hump silicone hose that absorbs thermal expansion in any direction, so the hose does not pop off, and the pipes have CNC machined connection ends that will not deform under tight clamps.
Features

- Lower pipe 60 mm (2 3/8 inch) and upper pipe 76 mm (3 inch), with smooth mandrel bends
- Flexible 3-hump silicone hose with aramid reinforcement and stainless steel rings between the upper and lower pipes

Fitting note
Space between the throttle body and the slam panel is very limited on G-chassis cars. In some cases the edge of the slam panel may need grinding back by a few millimetres to make room for the pipe.
