Expert's advice:
”The Mishimoto 2021+ BMW G8X M2/M3/M4 Performance Transmission Cooler excels with its impressive 41-percent increase in core volume, delivering superior cooling efficiency compared to the stock cooler and keeping your transmission cool even in the most demanding driving conditions. This transmission cooler also offers a generous 17-percent increase in fluid capacity to increase the cooling potential of the entire system. Internal cooling fins increase the surface area in contact with the fluid to improve heat transfer and efficiency. The dual-pass design keeps fluid in the cooler longer, removing more heat without affecting airflow to other cooling components behind the transmission cooler.
High fluid temps aren't the only worry on the track or the road, your transmission cooler sits front and center in the grille, taking every hit from road debris. That's why Mishimmoto included a durable steel stone guard to protect the trans cooler and keep fluid where it belongs. Installation is quick and easy, as no modifications are required. Like all Mishimoto products, the Mishimoto 2021+ BMW G8X M2/M3/M4 Automatic Transmission Cooler comes with the Mishimoto Lifetime Warranty.“
