How to replace the spark plugs on Ford Focus 1999-2007

Do it yourself, change the spark plugs on your Ford Focus, manufactured between the years 1999 and 2007. So the repair process should be the same on models produced in the years 2000, 2001, 2002, 2003, 2004, 2005 and 2006. You will need four new spark plugs from your local parts store, an 8 mm socket wrench and a spark plug socket wrench with an extension. In some cases it is better to have some dielectric grease, to apply on the ignition coils. The repair process is quite easy and it will not take you more than 25 minutes.
