AIRTEC Motorsport Billet Chargecooler Upgrade in Silver for BMW S55 - M2 Competition, M3, M4
Upgrade your BMW S55 cooling with the AIRTEC Motorsport billet chargecooler in Natural Silver. Designed, developed and manufactured in the UK, this top mount water-to-air chargecooler is a direct replacement performance upgrade for the BMW M2 Competition, F80 M3 and F82 F83 M4. Perfect for fast road and track use, it delivers lower intake air temperatures, resists heat soak and keeps power consistent run after run.
Why choose this BMW S55 chargecooler upgrade
This is not a basic like-for-like replacement. AIRTEC’s ultimate-specification chargecooler uses precision CNC machined billet aluminium end tanks with internal deflectors for smoother, freer flowing airflow across the entire core. The design maximises the largest core that can fit in the OEM top-mount location, improving cooling capacity and response while retaining all factory connections and the OEM dampened bracket.

Proven results on a high power S55
Back-to-back data logging on a tuned S55 running Littco L640 hybrid turbos at 648 bhp and 684 lb ft showed the following:
- OEM chargecooler: typical increase of 39°C in charge temps over a 2,000 to 7,500 rpm pull
- AIRTEC billet chargecooler: typical increase of just 9°C over the same pull
The result is dramatically reduced heat soak, lower intake temps and repeatable performance on the road and track.
