Installation Notes

Verify the hose routing, end style, and left-side valve cover to intake position before installation. Confirm the 12 mm inside diameter and 17 in. centerline length match the original hose on your vehicle. For BMW X5, BMW 545i, BMW 645Ci, BMW 745i, and BMW 745Li applications, inspect the mating ports and clips for wear so the replacement hose seats correctly.
