Mishimoto Performance Heat Exchanger with Rock Guard for G8X BMW M2 / M3 / M4 (AT)

Introducing the Mishimoto 2021+ BMW G8X M3 / M4 performance heat exchanger, the ultimate solution for maintaining optimal charge air temperatures under the most demanding conditions. In the realm of forced induction vehicles, air-to-water intercooling represents the future, and Mishimoto is pushing these advancements further. This design is entirely new, with no compromises, eliminating all plastic components in favor of durable aluminum end tanks, core, and CNC-machined ports. TIG-welded for maximum strength and longevity, this heat exchanger is built to withstand even the harshest conditions. Mishimoto has also incorporated strutted tubes within the core, providing unmatched resistance against bowing and flexing during aggressive cornering. Beyond strength, Mishimoto has increased the core volume by 23% and expanded the external fin surface area by 44%. Combined with a dual-pass flow configuration and louvered fin design, this performance heat exchanger significantly enhances cooling capacity over stock, boosting overall performance.

The Mishimoto Performance Heat Exchanger for the 2021+ BMW G8X M3 / M4 is engineered for a perfect fit with all other factory components, ensuring seamless integration into the vehicle. For additional protection, Mishimoto includes steel rock guards to shield the heat exchanger from debris, preventing punctured tubes or crushed fins. The Mishimoto G8X M3 / M4 performance heat exchanger is compatible with both automatic and manual transmissions. As with all Mishimoto products, this heat exchanger comes with a Mishimoto Lifetime Warranty, providing peace of mind and confidence in the investment. Upgrading the BMW G8X M3 / M4 with the Mishimoto Heat Exchanger offers a significant improvement in cooling efficiency.
