HEL Direct Fit Oil Cooler Kit for Subaru WRX STI (VA) 2.0/2.5 (2014-2021)

Every HEL oil cooler kit features a high-quality, reliable oil cooler manufactured by Setrab in Sweden. We have been using Setrab coolers for 10+ years, and have never had any issues with the performance or quality. Having an oil cooler fail or even burst is not something you want to experience, especially in demanding conditions and that is something we have never seen with Setrab's build quality. In the past, we've even had reports of front-end collisions and the Setrab oil cooler was the only component that still worked!

Delivered with pre-assembled braided hoses and Aluminium fittings, our comprehensive kit has everything required for a straightforward installation. Using AN8 high-flow performance hose to deliver and return oil from the external oil cooler, this kit also includes a bespoke oil filter take-off plate, which is equipped with a built-in thermostat. The thermostat ensures that your engine oil flows to the external oil cooler only when the oil reaches the desired temperature (92°C / 198°F).

Around 10% of the engine oil circulates through the oil cooler at any given time, this ensures a continuous flow that prevents air pockets and safeguards against thermal shock to the system. The surplus oil is then channelled back to the engine through the internal bypass system, promoting faster warm-up, providing added safeguarding in cold weather conditions, and eliminates the risk of overcooling.

Included with every kit is an easy-to-read installation manual. If you get stuck, our technical support team is always happy to answer any questions you may have.
