The hot-V configuration of the M8's twin-turbo setup generates phenomenal horsepower but also intense thermal loads under the bonnet. Upgrading your heat management ensures the S63 engine delivers consistent, unrestricted power without heat soak intervention. Increase your thermal efficiency by fitting high-capacity Chargecoolers and replace the vulnerable factory plastics with durable aluminum Boost Pipes. Ensure your engine oil and coolant remain perfectly balanced during high-speed continental cruising by installing upgraded Radiators and standalone Oil Coolers.
