Real results on a tuned S55
Back-to-back data logging on a tuned test car running Littco L640 hybrid turbos at 648 bhp and 684 lb ft showed dramatic improvements:
- OEM chargecooler: typical rise of 39 degrees across a 2,000 to 7,500 rpm pull
- AIRTEC billet chargecooler: typical rise of just 9 degrees across the same pull
This significant reduction in charge temperature helps maintain power run after run, reduces heat soak and supports reliable performance for track days and spirited fast road driving.
Built for S55 performance
This AIRTEC Motorsport billet chargecooler is engineered specifically for the BMW S55 engine platform. The precision-machined billet end tanks and internal deflectors optimise airflow across the full core length, improving intake charge cooling while maintaining smooth flow. The result is lower intake temperatures, improved consistency and enhanced reliability on tuned and standard cars alike.

Why billet aluminium
Billet aluminium allows ultimate precision inside and out. CNC machining ensures accurate internal airflow direction, a perfect seal to the core and a superior, high-quality finish. The result is a freer-flowing, higher-capacity chargecooler that resists heat soak and supports repeatable performance.
