AIRTEC Motorsport Chargecooler Radiator BMW M140i M240i 340i 440i B58

The Issue

As the performance of chargecooled engines depends on the temperature of the coolant inside the system, it’s very important to ensure it runs as cool as possible for as long as possible. As the standard system can struggle to maintain temperature, especially on a tuned application, the keys to ensuring a consistently lower running temperature are to increase the capacity of the system and its ability to cool it.

The Solution

AIRTEC Motorsport’s solution to improving the original setup with the limited space available behind the bumper was to extend it forwards by introducing a core that’s nearly 60mm thicker, at 90mm in depth. This allowed the use of a triple-pass core design to allow the coolant to pass through the radiator three times before it exits, with capacity increased to a huge 23.3 litres, compared to the original 7.7 litres; a gain of 203%.

Despite the huge cooling capacity increase that allows the chargecooler system to run cooler for longer, the radiator fits neatly behind the bumper and requires no modifications to fit, using the OEM mounts and the original coolant connectors. To protect the larger core in its vulnerable position at the front of the car, there is also a stone guard.

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