The Airtec Motorsport Radiator for the Ford Focus RS Mk3 is a replacement radiator with increased capacity, suitable for track use and sporty road driving. Drawing on its extensive experience with radiators for modified track and road cars, Airtec has opted for a direct replacement with a larger core, which makes optimum use of the available space in the original position.
The core is 15% larger than the original Ford core, delivering a significant increase in capacity: 12.99 litres compared to 11.34 litres for the original radiator. This is exactly what is needed when your Focus RS has been modified for more power, as more power naturally requires more cooling.
This lightweight solution consists of a 40 mm aluminium tube-and-fin core combined with welded aluminium end tanks. This design increases the capacity of the cooling system whilst improving efficiency, ensuring that the temperature remains lower during prolonged or heavy use than with an original radiator.
This also makes the radiator suitable for modified or track-focused vehicles that constantly operate at higher temperatures, and for warmer climates where cooling is a key consideration. As a direct replacement, the radiator fits onto the original mounting points and connections, making installation straightforward.
