Description
The Mishimoto MMOC-WRX-15BK is a direct-fit oil cooler kit built specifically for the FA20DIT-powered 2015+ Subaru WRX, pairing a 19-row bar-and-plate cooler core in a Stealth Black finish with application-specific brackets, a CNC-machined aluminum sandwich plate, and preassembled stainless steel braided lines. It bolts directly onto the WRX’s factory oil filter housing and front bumper opening without hacking up OEM components, giving you a genuine Mishimoto oil cooler kit rather than a generic universal setup.
Subaru’s turbocharged, all-wheel-drive WRX is a genuinely capable performance car, but its factory liquid-to-liquid oil cooler can fall behind once you start driving aggressively, modifying the engine, or spending time on track. This Mishimoto oil cooler works in conjunction with, and retains the use of, that stock liquid-to-liquid unit rather than replacing it, adding an external cooling path that helps stabilize oil temperature under sustained load. Mishimoto reports a +25 degree Fahrenheit (13.9 degree Celsius) drop in oil temperature with minimal pressure loss, and the kit also increases total oil capacity by 0.75 qt. As a complete, application-specific Mishimoto cooling kit, it’s designed as a full bolt-on oil cooling solution for street and track use, requiring no cutting or permanent modification for installation, and it’s backed by the Mishimoto Lifetime Warranty.
