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 induction sound, and a unique look in the engine bay.
This kit uses the largest filter combination that Airtec currently offers for the Focus Mk2 platform. At the heart of it all is the enormous 8-inch Cosworth Group A air filter, combined with one developed specifically for the Focus ST225 and RS 80 mm CNC-milled aluminium trumpet.
The combination of the large filter surface area and the generous 80 mm diameter creates an extremely free-flowing intake system that optimally supplies the turbo with air. The result is improved throttle response, more induction sound, and an impressive appearance under the hood.
The aluminum trumpet is finished in a durable black powder coating for a high-quality OEM+ appearance.
An optional installation can be selected 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 mounting the filter and the trumpet.
Additionally, there is an optional Airtec Motorsport ECU holder available. This high-quality plastic holder is designed as an affordable alternative to the original Ford part and ensures a neat OEM+ finish of the engine bay.
NB: If you already own a previous Group A kit, the new filter can also be ordered separately.
