Product Description
The S58 under the hood of the 2021+ G80 M3 has over 45 years of lineage behind it; like every generation before it, the G80 M3 has the potential to be even more powerful, but with great 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 designed as a combination intercooler/intake manifold design, which 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 lbs. 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 PSI.
Reliability aside, the Mishimoto charge air cooler's has further improvements; our core is 33% larger than stock, and the manifold flows an average of 14% 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 degrees 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 included a fiber gasket that insulates the runners from engine heat for those seeking every degree of cooling.
