Fits 2021-2026 BMW M2, M3, and M4 (Base, Competition, CS, and CSL).

Manage engine temperatures on your G8X platform with Mishimoto Performance Auxiliary Radiators. Sold as a pair, these radiators replace restrictive factory units to provide the increased cooling capacity required for high-performance driving and track conditions. The custom-engineered cores offer a 25-percent increase in volume over the stock components, ensuring more effective heat dissipation for both factory and modified S58 engines.

Engineered for durability, these radiators feature full-aluminum end tanks that are TIG-welded to the cores. The internal strutted tubes provide critical reinforcement against heavy vibrations and potential road debris impacts, a common failure point in performance applications. These units install into factory mounting points for a secure, direct-fit solution.
