AIRTEC Motorsport Side Radiators for BMW S55 (Right Hand Side)

As part of our expanding BMW platform product range, AIRTEC Motorsport is proud to launch our auxiliary radiator upgrade aimed at BMW M2 Competition/M3 & M4 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 both wider and thicker. This means capacity is increased by a 65% over standard, whilst frontal area is also increased by 13% 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. 

Furthermore, to protect the larger core in its vulnerable position at the front of the car, there is also a mesh stone guard fitted in place, as OEM radiators can often become damaged over time, which limits their cooling ability. 

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

Available as a pair, or individually.
