AIRTEC Motorsport Chargecooler Radiator Upgrade for BMW M2 Competition, M3 and M4 with S55 engine
Unlock reliable, repeatable power and reduce heat soak with this front mount AIRTEC Motorsport chargecooler radiator upgrade for the BMW M2 Competition, BMW M3 and BMW M4 S55. Perfect for fast road and track day use, this uprated chargecooler radiator dramatically improves coolant volume and cooling efficiency to keep intake temperatures under control, lap after lap and pull after pull.
On the S55, intake air temperature stability is everything. The standard chargecooler circuit can struggle, especially on tuned cars. AIRTEC’s engineered solution uses the maximum available space behind the front bumper to deliver a huge increase in capacity and frontal cooling area, helping maintain consistently lower IATs and stronger, more consistent performance.
Why this S55 chargecooler radiator upgrade is a must-have
- Massive capacity increase: 9.9 litres vs 4.5 litres OEM - over twice the volume to combat heat soak
- 40 percent larger frontal surface area for superior heat rejection and cooler intake temps
- Twin-pass core design for improved thermal efficiency and coolant dwell time
- Direct fit upgrade - uses OEM mounts and factory coolant connectors, no cutting or trimming
- Removable stone guard protects the larger core in its front-mounted position
- High quality powder-coated black finish with a comprehensive fitting kit and detailed instructions
We have fitted and used this AIRTEC Motorsport S55 chargecooler radiator on our own and customer cars. Feedback is consistently excellent: faster recovery between pulls, more stable IATs on spirited drives and track days, and stronger, more repeatable performance on tuned setups.
Optimised for BMW S55 cooling performance
This uprated charge cooler radiator is designed to work perfectly on the BMW M2 Competition, M3 and M4 with the S55 engine. It can be paired with the original chargecooler for a noticeable drop in temperatures. For maximum gains, combine it with AIRTEC’s Ultimate Specification billet chargecooler for the S55.
