Engineered for S63 M5 / M6 F1x and M5 F90, MMX Performance charge coolers use a large stepped tube-and-fin core that’s 28% larger per unit and roughly doubles cooling area vs OE. The result is consistently lower IATs, minimal pressure loss, and repeatable power without cool-down delays — ideal for stock through high-power builds.
MMX Performance’s charge coolers for S63-powered BMW M5 / M6 are engineered to deliver significant gains in power and torque by dramatically lowering charge air temperatures. Purpose-built around a large tube-and-fin stepped core, each unit offers roughly double the cooling area and a 28% increase in size per cooler versus OE. The factory S63 coolers struggle under higher power and sustained hard use, leading to rising IATs and measurable power loss; MMX Performance addresses this with a core developed specifically for the demands of F1x and F9x M cars. Development centered on the sweet spot between maximum IAT reduction and minimal pressure drop, enabling larger capacity without added lag. By consistently suppressing IATs and resisting heat soak, these race-proven charge coolers sustain repeatable performance without the cool-down recovery times typical of the stock system — making them a highly recommended upgrade for every stage of S63 tuning.
