The K&N HP2004 is fine. Have used it in the past on my Zetec. Unless you are using synthetic with longer drain intervals you are wasting your money though. My oil analysis with this K&N, and Oure One showed no noticeable differences after a year 8-9000 miles with a filter change at 6 months. $10 a pop is an expensive filter.
