As part of our expanding BMW product range, AIRTEC Motorsport is proud to launch our direct replacement aluminium undertray for the G-series M cars including M2, M3 and M4.

The original undertray on these cars is made from plastic and features a large opening to allow air to cool the engine’s oil cooler, which is mounted close to the floor. However, due to the oil cooler’s low-level placement and lack of protection from road debris that may flick up, it is left open and exposed to damage, which could cause imminent engine failure.

Our solution to creating a direct replacement undertray in aluminium began with a full 3D scan of the vehicle’s underside to ensure a perfect fitment that reuses all original mounting points.

As a result, it requires no drilling or cutting and is completely reversible if required. It also retains the original BMW rubber bumper trim. The laser-cut mesh section ensures no substantial debris can damage the oil cooler and our design also features an additional venting in the stepped section to further improve air flow.

Finished in a high-quality black powder coat finish, the undertray offers improved protection, durability and cooling effectiveness.

PLEASE NOTE: The under tray uses existing mounting points – but it is essential the fixings you use to secure it are of good quality. The original BMW fittings should only be used if they’re in good condition. Worn, corroded or broken fixings should be replaced with new items from BMW, as failure to do so may cause the undertray to work loose.
