Keep your 2021+ BMW M3/M4 cool and collected with the Mishimoto 2021+ BMW M3/M4 performance oil cooler. Much like their predecessors, the G8X M3 and M4 were designed with efficiency in mind. This can be a double-edged sword, as the optimally arranged engine bay has components placed in precarious positions. Most notably, the oil cooler is placed on the undercarriage, parallel to the road's surface. This placement increases air flow and uses aerodynamics to pull air through the core, but it also makes the stock cooler vulnerable to scrapes, bumps, and other road hazards.

With this in mind, the engineers at Mishimoto set out to design a robust G8X oil cooler to keep your M3 or M4 running cool on and off the track. We started by swapping the stock tube-and-fin cooler for a bar-and-plate with CNC-machined end tanks. Our cooler boasts a 35.7-percent thicker core and a 41-percent increase in core volume for superior cooling efficiency. Our cooler fits directly in place of the stock unit and retains the stock seals and bash guards for optimal airflow and additional protection.

The Mishimoto performance oil cooler for the 2021+ BMW G8X M3/M4 includes everything needed for installation and, as with all Mishimoto products, it's protected by the Mishimoto Lifetime Warranty for a lifetime of protection and cooling.
