Chargepipe-Intercooler O-Ring Seal, Coldside - E82 135i, E9X 335i, Z4 35i

This is a large o-ring that seals the coldside chargepipe from the intake to the front mounted intercooler on E82 135i, E90/E92 335i, E84 X1 28i/35i  and E89 Z4 28i. Without this seal, or if it's damaged, charged intake air coming from the cooler and result in a boost loss and poor performance. The seal has a more defined shape and is designed to fit a certain way over the intercooler inlet, which is why BMW calls it a preformed seal.

This part is listed by BMW as BMW part number 11617791469 (11-61-7-791-469) and is described as Genuine BMW Preformed Seal for charge air pipe (N20, N54, N55).
