Mishimoto 2021+ BMW G8X M3/M4 Performance Auxiliary Radiators

The strutted tubes in these Mishimoto auxiliary radiators are a notable design choice, offering extra reinforcement against the vibrations and impacts that high-performance driving can dish out. These radiators are specifically built for the 2021 and newer BMW G8X M2, M3, and M4 models, aiming to keep your engine temperatures in check, whether you're on the track or just pushing your car hard on the street.

Sold as a pair, these units feature full-aluminum end tanks that are TIG-welded to custom-engineered cores. This construction method ensures they are well-built and ready to handle the demands of your M car. You'll see a 25-percent increase in core volume compared to stock, which means more surface area for heat dissipation and more effective temperature regulation. This improved heat transfer is beneficial for both stock engines and those with modifications, helping to prevent overheating during spirited driving.

While these radiators offer robust construction, Mishimoto also makes steel stone guards available separately for additional protection against road debris. As with all Mishimoto products, these auxiliary radiators come with the Mishimoto Lifetime Warranty, giving you peace of mind for as long as you own your vehicle.
