MISHIMOTO MMINT-G80-21BK 2021+ BMW G80 M3/M4 PERFORMANCE INT

The S58 under the hood of the 2021 plus G80 M3 has over 45 years of lineage behind it, and it shows in nearly three-second 0 to 60 times and over 500 Horsepower. But like every generation before it, the G80 M3 has the potential to be even more powerful. Bolt-on mods, big turbos, and tunes can push the S58 over the 800 Horsepower mark, but that much power requires serious cooling. Luckily, Mishimoto has developed a charge air cooler manifold suited for serious power. The stock G80 M3 charge air cooler is... fine. The combination intercooler/intake manifold design is efficient, but it's let down by the tube-and-fin core crimped onto the thermoplastic plenum. Those crimps are quickly becoming a notorious weak point, with many failing at as little as 3 Pound. of boost over stock. The solution is Mishimoto's cast aluminum and TIG-welded manifold with a robust bar-and-plate core, designed to withstand boost pressures over 60 Pounds Per Square Inch without breaking a sweat. Reliability aside, the Mishimoto charge air cooler's performance possibilities are nearly endless. Our core is 33 percent larger than stock, and the manifold flows an average of 14-percent better to each cylinder. That, combined with the increased cooling capacity of the bar-and-plate core, results in reduced pressure drop and intake air temps as low as 11-Degree above ambient under heavy load. Our CFD-designed lower plenum also features an internal diverter to ensure the entire core is utilized and each cylinder receives even flow for safe and optimal fueling. The cast and CNC-machined runners feature O-ring grooves to accept factory seals, and we've provided a fiber gasket that insulates the runners from engine heat for those seeking every degree of cooling.
