The hand-built M139 2.0-litre engine is a masterpiece of modern forced induction, but it generates phenomenal under-bonnet temperatures, particularly when tuned for higher output. Optimizing your thermal management is critical to ensuring your four-door coupe delivers consistent power without the ECU pulling timing due to heat soak. Lower your intake air charge temperatures drastically by fitting high-capacity Chargecoolers, and keep your engine coolant vitals strictly regulated during continuous circuit driving with high-efficiency Radiators designed to handle the extreme thermal loads of this high-output AMG powerplant.
