The following guide outlines the procedure for replacing the spark plugs in the 2.0 and 2.3 liter Duratec engines found in 2004-2007 Focus models. Replacement for OEM spark plugs is suggested every 60,000 miles.
For spark plugs that have an adjustable gap between the electrodes, the suggested gap is 0.050". OEM Motorcraft double platinum spark plugs, which are used in this guide, come pre-gapped and cannot be altered.

Awesome guide. My Focus is exactly the same, Screaming Yellow! But can you put in a guide to change the air filter too?
I found out that standard-issue air filters for the ‘05-’07 Focus are lifetime 150k-mile filters, and shouldn’t need regular replacement. My parents’ Aerostar also had such a filter, so it may be a regular design feature in Ford vehicles. There’s a little gauge next to the filter housing: if the yellow line is still in the green, then there’s adequate airflow. If it’s in the red region, there’s a problem. I do not know if the car engine has to be on or not, but best check it in both states to be sure.
but what if i did what you had shown. an it works for the couple of days an then it starts to bang each time you put it in gears . its like it lose power then it comes back on.. have a ford focus 4cyl 2.0 engine
My focus st does not have power as I have just changed the spark plugs and I used the NGK ones . Are they the correct ones or can u recommend plugs to use .
Regards
