Description
Enhance your Subaru WRX’s engine cooling with the Mishimoto 2015-2018 Subaru WRX Thermostatic Oil Cooler Kit. Designed specifically for models from 2015 through 2018, this kit offers a full bolt-on solution that effectively reduces oil temperatures during both street and track driving. The included 19-row cooler, mounted in the front bumper with robust application-specific brackets, provides optimal airflow and cooling capacity. This setup helps maintain proper oil temperature, preventing overheating that can damage high-performance engines, especially under aggressive driving conditions or after modifications. The kit replaces the stock liquid-to-liquid oil cooler with Mishimoto’s sandwich plate featuring a rear-mounted thermostat, which activates at 185°F (85°C), ensuring oil remains within ideal temperature ranges. Proper regulation of oil temperature extends engine life and maintains performance, even during prolonged spirited driving sessions. The preassembled stainless steel lines with -10AN fittings ensure reliable oil flow to and from the cooler, with minimal pressure loss. The included silicone heat exchanger bypass hose offers a clean, integrated look in the engine bay. This oil cooler kit is available in sleek black or silver, allowing you to match your vehicle’s aesthetic. As part of Mishimoto’s commitment to quality, the product comes with a lifetime warranty, guaranteeing durability and performance under demanding conditions. Installation requires no modifications, making it an accessible upgrade that significantly improves your WRX’s cooling system and overall engine reliability.
