AIRTEC Stage 2 Induction Kit for Ford Focus MK3 ST250 – Facelift and Pre-Facelift
Upgrade your Ford Focus ST250 with the AIRTEC Stage 2 Induction Kit and unlock sharper throttle response, stronger mid-range pull and that addictive turbo induction sound enthusiasts love. This performance air intake replaces the restrictive OEM plastic airbox with a free-flowing setup designed to work perfectly with the standard Focus ST250. Real-world gains of approximately 5 to 10 bhp over the factory airbox are typical, along with a noticeable improvement in driveability and engine tone.
Whether you call it an induction kit, cold air intake, air intake kit or performance intake for the Focus ST, this AIRTEC Stage 2 system delivers. It enhances induction noise and produces a crisp recirculation dump-valve “psssh” on lift-off, while adding purposeful style under the bonnet. We’ve fitted and used this kit ourselves on Focus ST250 builds and our customers have been consistently impressed with the sound, fitment quality and performance improvement.
