Rvng (G80,G82,G87) S58 Upgraded Core Transmission Oil Cooler w/ Built in Rock Guard
RVNG Performance Transmission Cooler – 2021+ BMW G8X M2 / M3 / M4
The ZF 8-speed transmission in the G8X M2, M3, and M4 is a proven performer, capable of handling serious power from the S58 platform. But once you start pushing past stock—tuning, bolt-ons, track days—the factory transmission cooler quickly becomes a weak point. Elevated trans temps lead to sluggish shifts, reduced performance, and long-term wear. That’s where RVNG’s Performance Transmission Cooler steps in.
Engineered for maximum efficiency, our upgraded transmission cooler delivers a 41% increase in core volume over stock, keeping transmission fluid temperatures in check under the harshest conditions. A 17% increase in fluid capacity boosts the system’s overall cooling potential, while internal cooling fins maximize surface area for improved heat dissipation.
Featuring a dual-pass design, RVNG’s cooler keeps fluid circulating longer for better cooling without restricting airflow to surrounding components. Whether you’re carving canyons or chasing lap times, this upgrade ensures your ZF 8HP stays cool, responsive, and protected.
