Airtec Motorsport Auxiliary Radiator BMW M140i M240i F87 M2 340i 430i 440i B58 B46

As part of our expanding BMW platform product range, AIRTEC Motorsport is proud to launch our auxiliary radiator upgrade for the M140i, M240i, 340i and various other models for fast road or track use.

AIRTEC Motorsport’s solution to improving the original set up is utilise the available space behind the front bumper and develop a direct replacement radiator that’s wider, taller and thicker. This means capacity is increased by a 56% over standard, whilst frontal area is also increased to help cool the extra capacity.

Despite the significant increases, the radiator fits neatly behind the bumper and requires no modifications to fit, using the OEM mounts and the original coolant connectors.

Finished in a high-quality powder-coated black finish, the fitting kit includes a detailed installation guide.
