Description
The Mishimoto MMOC-WRX-08T is a direct-fit oil cooler kit engineered specifically for the 2008+ Subaru WRX, closing a factory gap on cars that leave the assembly line without any dedicated oil cooler. Built around a 19-row bar-and-plate core finished in anodized silver, the kit bolts into the front bumper using application-specific brackets and a CNC-machined aluminum spacer, and it’s designed to bring oil temperatures down by as much as 60 degrees with minimal pressure loss.
Whether your WRX has been modified or spends time on track, sustained heat in the oil is one of the fastest ways to shorten engine life, and this Mishimoto oil cooler kit is built to keep that heat in check. Preassembled stainless steel braided lines with -10AN fittings route oil from an M20 sandwich plate to the grille-mounted cooler, while a thermal reflective wrap deflects radiant heat from the exhaust away from the lines. Mishimoto notes a proven 25°F (13.9°C) drop in oil temperature, and the system is engineered to work in conjunction with the WRX’s factory liquid-to-liquid heat exchanger rather than replace it, so proper fluid warm-up and regulation are preserved. This oil cooler kit is offered with your choice of a Silver or Black cooler and a standard or thermostatic sandwich plate, giving you added control over how the system engages.
