Genuine OEM factory-original BMW front suspension strut mount tower covering cap (Part Number: 31-31-1-139-453 / 31311139453). This component is brand new old stock (NOS) and remains uninstalled inside its original factory distribution plastic packaging.
The label retains clear dealer tracking data alongside a handwritten storage marker notation reading: "Byzan E36 Strut Caps". This durable molded black plastic cap snaps firmly over the exposed front suspension upper strut guide support tower center hardware. It creates an essential environmental barrier that locks out road grime, salt spray, and moisture, successfully protecting vital suspension mounting bearings from premature structural rust while maintaining a neat, tidy underhood aesthetic.
