The AIRTEC Motorsport front mount chargecooler radiator upgrade is designed to keep your M3 running cooler for longer, whether on fast road drives or track sessions.
High-performance chargecooled engines rely on efficient coolant flow, and the standard system can struggle, particularly on tuned or modified cars. AIRTEC Motorsport’s solution is a larger, more capable radiator that dramatically improves cooling efficiency.
Built to make full use of the space behind the front bumper, the AIRTEC radiator is nearly 100mm taller and 20mm thicker than the stock unit. This provides a 5.4-litre increase in capacity – more than double the standard – and a 40% increase in frontal area, ensuring optimal cooling under sustained load.
Despite its larger size, the radiator fits directly using OEM mounts and coolant connectors, with no modifications required. A removable stone guard protects the core in its exposed front position.
Finished in a durable black powder-coated finish, the kit includes all fixtures, fittings, and detailed instructions. For best results, it can be used with the factory chargecooler or combined with the AIRTEC chargecooler upgrade for maximum cooling performance.
