BMW F97/F98, X3M/X4M Aluminum Alloy Oil Skid Plate

Protect the oil cooler on your BMW X3M or X4M with this Aluminium Alloy Oil Cooler Skid Plate — a formed alloy guard that replaces the flimsy factory undertray with something that will actually stop a stone.

The S58 runs its oil cooler low and forward, sitting exposed behind the front bumper with only a thin plastic tray between it and the road. On a car this heavy, with this much power, an oil cooler strike is not a cosmetic problem — it empties the sump at speed. Anyone who tracks an X3M or X4M, or drives one on Australian country roads, is one stone away from a very expensive morning.

This plate is formed from aluminium alloy with a honeycomb vented section over the cooler face, so the cooler still gets full airflow while everything behind it is shielded. Supplied with the mounting hardware and edge trim.

Key Features:

Formed Aluminium Alloy
Pressed and folded rather than flat cut, so the panel holds its shape under load instead of flexing at the mounts.

Honeycomb Vented Face
An open hex pattern directly over the cooler, protecting it without blanking off the airflow it exists for.

Replaces the Factory Tray
Mounts at the original locations in place of the standard plastic undertray. Nothing is added underneath.

Hardware and Edge Trim Included
Bolts, grommets and protective edge trim are supplied in the box.

Track Day Insurance
Far cheaper than an oil cooler, a tow and an engine inspection.

Direct Bolt-On Fitment
Uses the factory mounting points. No drilling and no cutting.
