Our inlet pipe is solid aluminum. It has machined ends to fit the OE turbo and intake. It also has an ear bracket which secures it to the motor. It was constructed using a fixture of the OE inlet pipe to ensure perfect fit. The flange for the intake system side is on a compound angle, so a normal 90 degree doesn't work correctly. Fits E82, E84, E88, E90, E92, E93 *These are built to order. Please allow at least 1 week for shipping. Any pipes ordered with expedited shipping will go out expedited after pipe is made.*
