Installation Notes

Verify the hose routing, end style, and inside diameters before installation. This hose uses push-in ends and is molded to match the original path, so correct alignment at the intake manifold connection is important. Inspect nearby ventilation components, seals, and fittings for wear before completing the repair. Confirm vehicle-specific fitment for your BMW 325Ci, 330i, or other listed application before ordering.
