Keep charge temperatures under control and performance at its peak with the AIRTEC chargecooler and front mount chargecooler radiator upgrade kit - designed, tested, and manufactured in the UK specifically for the BMW S55 engine. This comprehensive setup transforms the M3, M4, and M2 Competition’s cooling capabilities for both fast road and track use.
The chargecooler features the largest core available on the market, offering an impressive 125.6% increase in volume and a 45.3% increase in frontal area over the standard unit. Paired with the upgraded front-mounted radiator, which is nearly 100mm taller, 20mm thicker, and delivers over double the coolant capacity (a 5.4-litre increase), this system dramatically improves cooling efficiency, reduces heat soak, and maintains consistent power delivery under demanding conditions.
Both components are precision-engineered with high-flow cast aluminium end tanks, finished in durable black powder coat, and designed for straightforward, direct-fit installation using the factory mounts and connectors. The radiator includes a removable stone guard for extra protection, while the chargecooler retains OEM fit and finish for a clean, factory-style look.
Whether used individually or together, these AIRTEC Motorsport upgrades deliver exceptional cooling performance and reliability, ensuring your engine performs at its best on the road and the track.
Note: M2 Competition models require minor trimming under the bonnet due to the increased chargecooler size.
