MMR Twin Chargecoolers for BMW M5 M6 F10 F12 F13 F90 S63 2011-2023 - MMR05-1002 - MMX Twin chargecoolers for BMW F1x S63 The MMX Performance chargecoolers for S63-powered BMW M5 & M6 F1x plus M5 F90 improves power and torque output significantly by substantially reducing charge air temperatures. Using a large tube and fin stepped core, these coolers provide literally double the cooling area and are 28% larger in size per cooler vs OE. The factory charge coolers used on the S63 engine have proved to be unable to cope with the demands of higher power, hard driven cars, showing up as serious power losses during hard driving as air intake temperatures soar. Our massive replacement chargecoolers are the best performing cooler upgrade on the market for the BMW S63. The intercooler core was developed specifically for the high requirements of the F1x & F9x M-Cars. Using a large tube and fin stepped core, our performance chargecoolers provide double the cooling area and are 28% larger per cooler than OE. Our development focussed on finding the ‘sweet spot’ of maximum IAT cooling versus minimum pressure loss. This has allowed us to achieve increased size without increased lag. By consistently reducing intake air temperatures (IAT), heat soak is minimised delivering increased performance again and again. No need for the recovery cool-down times needed for the production cooler. This race-proven cooler really is essential for every stage of tuning on any high performance S63-engined M-Car. Features A 28% increase in core size per chargecooler vs the OE chargecoolers. Delivers substantial temperature drop across the core, with minimal impact on pressure drop. Designed and engineered in the UK. Anti-corrosive thermal coating. Easy installation, no cutting or permanent modification to the vehicle required. Additional Information The core itself uses internal turbulators to improve its cooling performance and the CFD optimised cast end tanks assist with maintaining the best possible airflow across the core.
