Mk3 Focus RS Oil Cooler Kit - Fully Fitted at mountune HQ

The mountune oil cooler upgrade for the Mk3 Focus is capable of providing a substantial reduction and, subsequent control of engine oil temperatures, even in the harshest of high-performance driving environments.

The kit features a durable oil cooler assembly that utilises a twin-pass core, a thermostatically controlled billet oil take-off plate, mountune braided race lines and all required race fittings, hardware, gasket and low-profile oil filter.

The cooler mounts via a low-profile bracket that positions it centrally to the upper aperture in direct air-flow; the size and positioning of the cooler has also been carefully considered to ensure there is no detrimental performance to the water radiator / cooling pack behind it.

The ultimate oil cooler setup for any Focus ST / RS owners that want to be able to enjoy their Focus to the full, when used on the road or track.

    Great product. Excellent instructions. Perfect construction & placement. If you are worried about high oil temperatures then this is a great product. Water temp does not seem affected by its central placement in front of the radiator. Also Thanks to Jay Sanford for assisting with my questions. Great product, great service, great people.
