Airtec Motorsport BMW S55 Chargecooler Radiator Upgrade (M3/M4/M2 Comp)

Airtec Motorsport BMW S55 Chargecooler Radiator Upgrade ensures your N55's coolant maintains a cool temperature for as long as possible, helping your intake system to resist heat-soak and consistently perform at its full potential.

Airtec have achieved this by developing a chargecooler radiator that measures nearly 100mm taller and 20mm thicker overall, compared to the OEM item. The uprated 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 removable stone guard.

The larger radiator can be used with the original chargecooler to improve running temperatures however, to see the biggest performance gains, we recommend using the radiator in conjunction with Airtec's Billet Chargecooler Upgrade for the S55 engine, also available on the R44 Performance website.
