The S58 under the hood of the 2021+ G80 M3 has over 45 years of lineage behind it, and it shows in nearly three-second 0-60 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 HP 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 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 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-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.; ----Insane power levels require equally insane amounts of fuel, so we've added provisions for port fuel injection, including a billet fuel rail and anodized aluminum injector blanks to cap the injector ports when not in use. Our precision-machined injector ports feature optimized geometry for the perfect mixing of air and fuel, with no drilling required. The included PTFE -AN fuel lines and fittings are suitable for ethanol and tee into the stock fuel lines. Additionally, six nitrous ports accept 1/8 or 1/16-NPT nozzles and can be capped off when not in use.----If cooling, flow, and reliability weren't enough, we also designed our charge air cooler to fit like stock. This kit includes brackets to keep your wiring tidy, a mount to fit the stock engine cover, and custom EVAP lines for a seamless installation. A convenient cutout in the plenum allows for easy access to the oil filter, without affecting flow. Like all Mishimoto products, this performance charge air cooler for the 2021+ BMW G80 M3 is backed by our Mishimoto Lifetime Warranty for a lifetime of exceptional performance. So if you want the ultimate upgrade to squeeze serious power from your S58 engine, this Mishimoto charge air cooler manifold is for you.
