After the success of our direct fit MK3 Focus RS oil cooler kit we started looking at other cars that would benefit from the same treatment. With the GR Yaris being one of the hottest cars of the year we knew we had to get one in.

Again we knew that we wanted to create an easy to fit oil cooler kit, so we 3D scanned the engine bay to find the best solution. As a result, we manufactured a custom aluminium bracket to mount the oil cooler on the crash bar using the OEM mounting points. The cooler then sits in direct air flow behind the top grill, the perfect location for effective cooling.

We based the kit around the popular Swedish-manufactured Setrab Series 6 ProLine oil cooler. The 10 row option gives a great balance between minimising pressure loss while giving very effective cooling. We also decided to offer an optional upgrade of a 9 Series for the dedicated track car.

We've been using Setrab oil coolers for over 10 years without any issues and their performance is unrivalled. There are lots of cheaper imported options available, but none as reliable (there aren't many things worse than having a burst oil cooler!). In fact, we've had reports of front end collisions and the Setrab oil cooler was the only thing that still worked!

This comprehensive kit arrives with preassembled HEL braided hoses and anodised aluminium fittings. These AN10 high flow performance hoses deliver and return oil from the oil cooler to our own HEL Performance Billet thermostatic sandwich plate set at 92°C (197.6°F). We've found the 92°C option gives you the perfect balance between cooling when needed and letting the engine warm up safely. It's also dangerous for the oil to be too cold and the thermostat controls the temperature with precision.

Our 6 Series cooler kit has had extensive testing, with fast road use and track time, recently managing 10hot laps without any significant rise to oil temperature.

This direct-fit kit offers a safe and reliable cooling system for the GR Yaris. It comes complete with easy-to-understand instructions and our technical support team are always happy to answer any questions you may have.
