The biggest performance air filter company in the world is now offering a super-trick replacement high-flow airbox for all Focus Mk2 and 3 motors and the equivalent cars from Volvo, even down to the 1-litre variants.
They are said to offer a guaranteed hike in bhp and throttle response, for those who either don’t like the noise associated with induction kits, or that live in countries like Germany where you run the risk of being marched off to prison for fitting anything that isn’t TUV-approved.
This particular item also comes with an added end cap that can be removed for added airflow (once you’re over the French border) and K&N’s world famous Million Mile Warranty. One of the best, from one of the best!
