The Airtec Motorsport Radiator for the Ford Focus RS Mk3 is a replacement radiator with increased capacity, suitable for track use and sporty street use. Based on extensive experience with radiators for modified track and street cars, Airtec has opted for a direct replacement with a larger core that makes optimal use of the available space in the original position.
The core is 15% larger than the original Ford core and thereby delivers a substantial increase in content: 12.99 liters compared to 11.34 liters of the original radiator. That is exactly what is needed when your Focus RS has been modified for more power, because more power logically requires more cooling.
The lightweight solution consists of a 40mm tube-and-fin aluminum core in combination with welded aluminium end tanks. This design increases the capacity of the cooling system and simultaneously improves efficiency, keeping the temperature lower during prolonged or heavy use than with an original radiator.
This makes the radiator suitable for modified or track-oriented vehicles that constantly run at higher temperatures, and for warmer climates where cooling is a concern. As a direct replacement, the radiator connects to the original mounts and connections, making installation simple.
