The Mishimoto 2021+ BMW M3/M4 G8X Performance Heat Exchanger is a direct-fit upgrade designed to improve your vehicle's cooling system. The heat exchanger is designed to be a direct fit replacement for the factory heat exchanger and is compatible with all 2021+ BMW M3/M4 G8X Automatic models.

Presenting the Mishimoto 2021+ BMW G8X M3/M4 Performance Heat Exchanger – a definitive solution for maintaining charge air coolness even in the most strenuous conditions. In forced induction vehicles, the trajectory leads toward air-to-water intercooler, and Mishimoto is at the forefront of this evolution.

Beginning from scratch with no room for compromise, the design dispenses with all plastic components, substituting them with robust aluminum end tanks, core, and precision CNC-machined ports. Welded meticulously using TIG techniques for maximum durability, this heat exchanger is engineered to endure even the harshest environments. The innovation extends further, integrating strutted tubes within the core for unparalleled resistance against bowing and flexing during aggressive cornering.

Strength, however, is not the sole objective. An impressive 23 percent has amplified the core volume, while the external fin surface area has expanded by 44 percent. With our dual-pass flow arrangement and louvered fin design, this performance heat exchanger drastically amplifies cooling capacity compared to the stock counterpart, resulting in elevated overall performance.

Rest assured, the Mishimoto Performance Heat Exchanger for the 2021+ BMW G8X M3/M4 is meticulously designed to integrate seamlessly with all other factory components. This ensures a perfect fit and smooth assimilation into your vehicle. For added safeguarding, we provide steel rock guards that shield the heat exchanger from debris, thus averting potential tube punctures or fin damage. 

Our renowned Mishimoto 2021+ BMW G8X M3/M4 Performance Heat Exchanger includes our famous Mishimoto Lifetime Warranty, offering you tranquility and confidence in your investment. Elevate your BMW G8X M3/M4 with the Mishimoto Heat Exchanger and embrace the potent advantages of enhanced cooling efficiency.
