AIRTEC Motorsport Secondary Intercooler for Ford Focus ST Mk4
Enhance the cooling performance of your Ford Focus ST Mk4 with the AIRTEC Motorsport Secondary Intercooler, engineered for track and fast road use. Developed in-house at AIRTEC HQ in the UK, this secondary intercooler is designed to reduce charge temperatures, improve heat rejection, and optimize overall engine performance without requiring modifications to your car.
The Challenge:
The Mk4 Focus ST’s upper grille area has limited space due to the intake system and ducting, making it difficult to fit a full-size front mount intercooler. While AIRTEC Motorsport offers a deeper intercooler upgrade, there was still potential to further enhance cooling efficiency without cutting or modifying the vehicle.
The Solution:
The secondary intercooler mounts neatly beneath the car behind the undertray and receives a direct feed of fresh air through a dedicated duct. By adding a secondary unit in place of the existing pipework section, the total intercooler capacity is significantly increased, complementing the original or upgraded intercooler setup. The kit includes Pro Hoses silicone pipes, all necessary fixtures and fittings, and detailed step-by-step instructions for a bolt-on installation. The upgrade is fully reversible, allowing you to return to the standard setup at any time.
Proven Performance:
Back-to-back testing on consecutive road runs demonstrated a 41% improvement in heat rejection and a 50% reduction in charge temperatures when the secondary intercooler was installed, confirming its effectiveness and efficiency in enhancing engine cooling under demanding conditions.
