Introducing the Mishimoto 2021+ BMW G8X M3/M4 performance heat exchanger, the ultimate solution to keep your charge air cool under the most demanding conditions. In the world of forced induction vehicles, air-to-water intercooling is the future, and Mishimoto are taking it to the next level.

We started from scratch, leaving no room for compromise. Our design eliminates all plastic components, replacing them with durable aluminum end tanks, core, and CNC-machined ports. TIG-welded for maximum strength and longevity, this heat exchanger will withstand even the harshest conditions. We took it further by incorporating strutted tubes within the core, adding unparalleled resistance against bowing and flexing during aggressive cornering.

But strength is not our only focus. We've increased the core volume by 23 percent and expanded the external fin surface area by 44 percent. Combined with our dual-pass flow configuration and louvered fin design, this performance heat exchanger vastly improves cooling capacity over stock, enhancing overall performance.

Rest assured, the Mishimoto Performance Heat Exchanger for the 2021+ BMW G8X M3/M4 is designed to fit perfectly with all other factory components, ensuring seamless integration into your vehicle. For added protection, we include steel rock guards to shield the heat exchanger from debris and prevent punctured tubes or crushed fins. The Mishimoto G8X M3/M4 performance heat exchanger fits both automatic and manual transmissions.
