BMW S58 Performance Charge Air Cooler Manifold

The S58 engine in the 2021+ BMW G80 M3 and G82 M4 is already an engineering powerhouse, delivering over 500 horsepower and blistering 0-60 times. But as with every M engine before it, there’s always more power to be unlocked. With the right upgrades—bolt-ons, bigger turbos, and tuning—the S58 can push past 800 HP. However, that kind of performance demands serious cooling. That’s where Mishimoto’s charge air cooler manifold comes in.

The stock charge air cooler gets the job done, but it has its limits. The factory tube-and-fin core, crimped onto a thermoplastic plenum, is a known weak point—many fail with as little as 3 psi over stock. Mishimoto eliminates that risk with a fully cast aluminum and TIG-welded manifold, featuring a robust bar-and-plate core built to handle over 60 psi of boost.

Beyond durability, this charge air cooler is designed for maximum performance. The core is 33% larger than stock, improving cooling efficiency and reducing pressure drop. Internal airflow is optimized, flowing an average of 14% better to each cylinder. The result? Lower intake air temps—just 11°F above ambient under heavy load—ensuring more consistent power delivery. A CFD-designed lower plenum with an integrated flow diverter ensures even distribution across all cylinders for optimal fueling and safe power gains. Mishimoto also includes a fiber gasket to insulate the runners from engine heat, squeezing out every degree of cooling efficiency.

For those pushing the limits, Mishimoto’s charge air cooler also integrates port fuel injection support. It includes a billet fuel rail and anodized injector blanks, so you can easily add fueling without any drilling. The precision-machined injector ports are optimized for proper air-fuel mixing, and the included PTFE -AN fuel lines are ethanol-compatible. Six nitrous ports (1/8 or 1/16-NPT) provide additional flexibility for power-hungry builds.

Mishimoto engineered this upgrade for a seamless fit. It includes brackets to keep wiring organized, a stock engine cover mount, and custom EVAP lines for hassle-free installation. Plus, a convenient oil filter cutout allows easy maintenance without sacrificing airflow. Backed by Mishimoto’s Lifetime Warranty, this charge air cooler manifold is the ultimate upgrade for serious S58 builds.

If you're looking to maximize cooling, airflow, and reliability for high-horsepower applications, 5150 AutoSport has you covered with the Mishimoto Charge Air Cooler Manifold for the BMW G80 M3 and G82 M4.
