Airtec Motorsport Group A induction kit for the Ford Focus ST225 Mk2 and Focus RS Mk2, developed for enthusiasts who want to combine maximum airflow, a more aggressive Intake sound and a unique look in the engine compartment.
This kit utilises the largest filter combination currently offered by Airtec for the Focus Mk2 platform. At its heart is the enormous 8-inch Cosworth Group A air filter, combined with an 80 mm CNC-machined aluminium trumpet developed specifically for the Focus ST225 and RS.
The combination of the large filter surface area and the generous 80 mm diameter creates an extremely free-flowing Intake system that supplies the turbo with an optimal air supply. The result is improved throttle response, more induction noise and an impressive look under the bonnet.
The aluminium trumpet is finished in a durable black powder coating for a high-quality OEM+ look.
For installation, you can opt for an optional 80 mm Pro Hoses silicone hose, available in black, blue, red, yellow and orange. This hose has been specifically developed for this Group A setup and is required for fitting the filter and the trumpet.
In addition, an optional Airtec Motorsport ECU mount is available. This high-quality plastic mount is designed as an affordable alternative to the original Ford part and ensures a neat OEM+ finish in the engine compartment.
Please note: if you already own a previous Group A kit, the new filter can also be ordered separately.
