K&N's 57S Performance Airboxes increase horsepower and acceleration by dramatically reducing air flow restriction caused by the original factory design. They come with K&N's Million-Mile Limited Warranty. 57S series airboxes replace the factory air filter housing with a fully enclosed injection modified air box containing a reusable K&N air filter. Installation is easy as they are specifically engineered to use factory holes and mounting points. No additional hardware, cutting or drilling is required. [MORE]

 Fitted to 163PS TDCI MK3 Focus, previously used the E-2993 filter in my MK2.5 TDCI Focus, and could have used it in my MK3, but decided I wanted a little more performance and growl from my diesel. Easily fitted, performs great and more so when pushing the car with a Bluefin remap up to 185PS. I have cleaned it once so far and it has been fitted now for 7 months. Well worth the upgrade.
