Mishimoto 2015+ Subaru WRX Thermostatic Oil Cooler Kit - Black

Enhance your 2015-2021 Subaru WRX's engine cooling performance with the Mishimoto Thermostatic Oil Cooler Kit. Designed specifically for the turbocharged FA20 DIT engine, this full bolt-on solution helps maintain optimal oil temperatures during aggressive driving and track days, thereby extending engine life and improving reliability. The kit replaces the stock liquid-to-liquid oil cooler with a high-capacity 19-row cooler mounted at the front of the vehicle, utilizing application-specific brackets for a secure fit. The included silicone heat exchanger bypass hose ensures a clean, professional look inside the engine bay while facilitating smooth oil flow.
The core component, a sandwich plate with a rear-mounted thermostat, activates at 185°F (85°C) to regulate oil temperature automatically. This feature helps prevent overheating during high-stress conditions, especially beneficial for modified vehicles or those frequently driven on the track. Preassembled stainless steel lines with -10AN fittings direct oil efficiently to and from the cooler, minimizing pressure loss and ensuring consistent cooling performance. Proven to reduce oil temperatures by approximately 20°F (11°C), this kit provides a reliable cooling upgrade without requiring modifications for installation.
Available in sleek black or silver, the Mishimoto WRX oil cooler kit combines durability, performance, and ease of installation. As with all Mishimoto products, it is backed by a lifetime warranty, ensuring long-term protection for your high-performance vehicle. Whether for street driving, spirited canyon runs, or track days, this oil cooler kit ensures your engine remains at the optimal operating temperature, maximizing power output and engine longevity.
