The S63B44 4.4-litre V8 engine utilizes a hot-V turbocharger configuration that produces incredible power, but also immense under-bonnet heat. Upgrading your thermal management is essential, particularly if you are tuning for higher boost. Lower your intake air temperatures and protect against heat soak by fitting high-performance Chargecoolers paired with durable, smooth-flowing aluminum Boost Pipes. Keep your engine oil and coolant temperatures strictly regulated during aggressive driving with high-efficiency Radiators and standalone Oil Coolers, ensuring your super saloon delivers consistent power pull after pull.
