Technical Data
As part of our expanding BMW product range, AIRTEC Motorsport is proud to launch our replacement uprated radiator for the E90, E92 and E93 M3 models, suitable for track or fast road use.
With huge experience in developing uprated radiators for a variety of modified track and road cars, we chose to create a direct replacement radiator with a larger core to make the most of the space available in the original location.
As a result, our radiator offers a huge capacity increase, thanks to a core that measures 25% bigger than the standard BMW core.
Our lightweight radiator solution also features a tube-and-fin aluminium construction together with welded aluminium end tanks. This design increases the cooling system’s capacity as well as improving its efficiency, allowing it to retain lower running temperatures compared to an original unit during prolonged or hard use. It’s also suited to modified or track orientated vehicles that operate with constant higher temperatures, or for hotter climate countries, where cooling can be an issue.
Designed as a direct replacement item, fitting is a simple process, making it a great addition to improve cooling.
TESTED
Testing was conducted on our Club Sport BMW E92 M3 track car at Brands Hatch circuit in June 2025. The day began with the original radiator installed on the car before swapping over to our replacement AIRTEC Motorsport aluminium radiator. Each radiator was run for two track sessions and coolant temperature was measured with an external thermocouple sensor with an advanced sampling rate.
With the standard radiator saw an average temperature of 91.4°C and with the AIRTEC Motorsport aluminium radiator we saw 83.9°C resulting in an average reduction of 7.5°C or 9% reduction in coolant temperature, the maximum temperature difference was 10.7°C.
