Toyota A90/A91 MK5 Supra Aluminum Alloy Oil Skid Plate

Protect the oil cooler on your Toyota GR Supra with this Aluminium Alloy Oil Cooler Skid Plate — a formed alloy guard that replaces the factory plastic undertray with something that will actually stop a stone.

The B58 sits its oil cooler low and forward behind the front bumper, with only a thin moulded tray between it and the road. A stone through an oil cooler at speed empties the sump in seconds, and on a car that spends time at track days that is not a remote risk. The factory tray is there to manage airflow, not impacts.

This plate is formed from aluminium alloy with louvred vent sections over the cooler face, so it extracts hot air and keeps the cooler fed while shielding everything behind it. Supplied with the mounting hardware and a blanking plate.

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.

Louvred Vent Sections
Four raised louvre banks that extract hot air from the engine bay while keeping debris out.

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

Hardware and Blanking Plate Included
All bolts, grommets and the access blanking plate 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.

Performance Benefits:

Shields the oil cooler from stone and debris strikes

Louvred venting extracts engine bay heat rather than trapping it

Stiffer and far more impact resistant than the factory plastic tray

Tidies up the underside of the car

Corrosion resistant aluminium with a durable black finish

Vehicle Fitment:

Toyota A90 / A91 GR Supra (2019+)

BMW Z4 M40i - G29 (2019+)

3.0L Turbocharged B58 Engine

Also Fits the BMW Z4:

The A90 Supra and the G29 Z4 were developed together and share their front structure, undertray mounting and B58 cooling layout, so this plate fits both. If you have a Z4 M40i, select it from the dropdown above.

Please Note:

Professional installation is recommended. The factory undertray is removed and retained — this is fully reversible.
