As part of our expanding BMW platform product range, AIRTEC Motorsport is proud to launch our oil cooler kit for the M140i models.

Developed in-house at AIRTEC HQ in the UK, we’ve created a comprehensive solution to improving the car’s oil cooling ability for modified M140i owners who struggle to maintain steady oil temperatures on track, or during fast road use.

With vast experience in developing uprated oil cooler packages for a variety of modified track and road cars, the challenge with this kit was to integrate a large capacity, external oil cooler neatly behind the available space behind the lower bumper grille area.

We began with a 3D scan of the car so we could use a CAD program to calculate the most efficient use of space with a perfect fitment.

As a result, our oil cooler kit utilises all original fixing locations, so no drilling is required to mount the oil cooler. It also features a large scoop that channels a constant flow of cold air in from the front bumper grille and out through a laser cut grille we provide to fit neatly inside the inner wheel arch liner.

In order to provide sufficient air flow required to the oil cooler, you can either choose to trim your original bumper grille to open it up or you can buy a direct replacement grille from BMW that is already opened up – BMW part numbers:
51 11 8 077 259 (without parking sensors)
51 11 8 085 309 (with parking sensors)

The comprehensive package also includes a bespoke AIRTEC Motorsport adapter plate to separate the oil and coolant systems, laser-cut and powder coated mounting brackets, a horn relocation bracket, high-quality braided hose lines with Aerotec fittings as well as all fixtures required to fit, including detailed instructions for a bolt-on installation.

Its improved cooling efficiency and fitment make it an essential modification for all modified M140i models used on track/hard road use.

Please note:
– This is a motorsport product and you may notice an increase in engine harmonics through the cabin when fitted
– Trimming/cutting of the inner wheel arch liner is required to fit this product
