AIRTEC Motorsport side radiators for BMW S55 (right side) - part number ATRADBMW4

Description

Technical Data

As part of our expanding BMW platform product range, AIRTEC Motorsport is proud to launch our auxiliary radiator upgrade for the BMW M2 Competition/M3 and M4 models for fast road or track use.

To improve on the stock configuration, AIRTEC Motorsport optimized the space available behind the front bumper and developed a direct replacement radiator that is both wider and thicker. This increases capacity by 56% compared to the standard version, while the frontal surface area is also increased to promote cooling.

Despite the significant increases, the radiator fits perfectly behind the bumper and requires no modifications to fit, using the OEM brackets and stock coolant connectors.

Additionally, to protect the larger core in its vulnerable position at the front of the car, a mesh rock guard is also fitted, as OEM radiators can often become damaged over time, limiting their cooling capacity.

Finished with a high quality powder coated black finish, the complete fitting kit includes a detailed fitting guide.

Available as a pair or individually.

CAUTION: Left and right sides are determined by looking into the engine compartment.
