Mishimoto MMINT-G80-21BK Performance Charge Air Cooler Manifold for 2021-2025 BMW G80/G82 M3 & M4 S58

Mishimoto Performance Charge Air Cooler Manifold – BMW G8X M3 / M4 (S58)

Part Number: MMINT-G80-21BK

The Mishimoto Performance Charge Air Cooler Manifold for BMW G8X M3 and M4 models is engineered for high-boost reliability, improved airflow, and superior charge-air cooling. Designed as a direct-fit replacement for the factory intercooler/manifold assembly, this upgraded unit eliminates the known weak points of the OEM plastic design while dramatically increasing cooling efficiency and flow balance—making it ideal for both aggressively tuned street cars and race-focused builds.

Constructed from a cast aluminum intake manifold TIG-welded to a robust bar-and-plate intercooler core, this system is rated for boost pressures up to 60 PSI and supports power levels up to 1,150 horsepower. Advanced CFD modeling ensures even airflow distribution to each cylinder, promoting consistent fueling, lower intake air temperatures, and improved engine safety under high load.
