HEL Direct Fit Oil Cooler Kit for Ford Focus MK3 RS/ST

When one of our employees experienced high oil temps in his own RS, we knew we had to help him develop the ultimate oil cooler kit. After a period of successful testing, it's now available for you to buy.

We knew straight away RS enthusiasts wouldn't want to drill or cut anything to fit an oil cooler, 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 13 row option gives a great balance between minimising pressure loss while giving very effective cooling.

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 a trusted Mocal 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.

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