AIRTEC Motorsport Large Group A Filter for Focus MK2 ST 225

AIRTEC Motorsport’s large cotton filter with a specifically machined alloy trumpet designed to fit the Mk2 Focus ST225. Our biggest trumpet and air filter combination yet, we created this kit to allow the fitment of the largest filter available on the market. If you already have a Group A kit and would like the newer filter design only, we offer the filter alone with the options of either with or without the Pro Hoses silicone connector and AIRTEC Motorsport replacement ECU holder.
