Product Description
Your 2001-2007 Subaru WRX or WRX STi was built for rally-inspired performance, but when you’re pushing the limits—whether it’s hard pulls, aggressive canyon runs, or back-to-back track days—heat becomes your biggest enemy. High oil temperatures can lead to power loss, reduced engine efficiency, and long-term wear, cutting into the reliability of your legendary EJ20 or EJ25 engine. That’s where the Mishimoto Performance Oil Cooler Kit comes in—designed to keep oil temps in check, extend engine life, and maximize horsepower output so you can drive harder, longer, and with total confidence.
This high-performance oil cooler system features a large bar-and-plate core, designed for superior heat dissipation and increased oil capacity. Whether you’re launching off the line or tackling grueling mountain passes, this kit ensures optimal lubrication and temperature control, reducing thermal breakdown and preventing heat-induced power loss. The kit includes high-flow stainless steel braided lines, durable CNC-machined fittings, and an innovative thermostatic sandwich plate that regulates oil temperatures for year-round performance. Built for a direct bolt-on fit, this cooler is engineered for seamless integration with 2001-2007 Subaru WRX and STi models, requiring no modifications for installation.
Available in sleek silver or stealthy black, and backed by the Mishimoto Lifetime Warranty, this is the ultimate cooling upgrade for any Subaru enthusiast who refuses to compromise on performance. Don’t let heat rob your power—upgrade your WRX or STi today and stay cool, stay fast, and stay ahead of the pack!
