Due to the restricted space within the upper grille area caused by the car’s intake system and ducting, it isn’t possible to install a full-size front-mount intercooler that spans the entire height of the grille. While AIRTEC offer a deeper intercooler upgrade for the ST, they wanted to explore additional ways to improve cooling efficiency and reduce charge temperatures without requiring any cutting or modification to the vehicle.
The answer was to create a secondary intercooler system that mounts discreetly beneath the car, behind the undertray, and is fed with fresh air via a dedicated duct. By integrating this secondary intercooler in place of a section of the existing pipework, they achieved a substantial increase in overall system capacity and improved cooling performance, while maintaining compatibility with both the factory and AIRTEC upgraded intercoolers.
Despite the significant improvement in cooling ability, the system fits neatly behind the undertray and can be fully reverted to standard without issue. The comprehensive fitting kit includes Pro Hoses silicone pipes, all required fixtures and fittings, and detailed step-by-step installation instructions for a simple and effective upgrade.
