 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.
