Mishimoto 2008-2014 Subaru WRX STI Thermostatic Oil Cooler Kit - Black

Enhance your Subaru WRX STI's performance and engine longevity with the Mishimoto 2008+ Subaru WRX STI direct-fit oil cooler kit. This high-quality kit features a large 19-row cooler that mounts seamlessly in the front bumper, delivering optimal airflow and cooling efficiency. By reducing oil temperatures by up to 30 degrees Fahrenheit, it helps maintain consistent power output and prevents overheating during spirited driving or track use. The included stainless steel lines with -10AN fittings and direct-fit mounting brackets ensure a straightforward installation process, saving you time and effort. The kit also comes with thermal reflective wrap for the oil lines, providing additional heat protection from nearby exhaust components, which is crucial for maintaining oil integrity in demanding conditions. Available in black or silver, the cooler can be customized to match your vehicle's aesthetic preferences, and the optional thermostatic sandwich plate offers even greater control over oil temperatures. As with all Mishimoto products, this kit is backed by a lifetime warranty, ensuring long-term reliability and peace of mind. Designed specifically for Subaru models from 2008 to 2014, including Impreza WRX STI variants, this oil cooler kit is an essential upgrade for enthusiasts seeking improved cooling and enhanced engine durability. It retains the use of your stock liquid-to-liquid oil cooler, providing a seamless fit without compromising existing systems. The minimal pressure loss and significant temperature reduction make this kit a practical and effective solution for street and track applications alike.
