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.

Use compressed air to clear any debris from the area around the ignition coils on top of the engine.

-
Apply dielectric grease to the ribbed portion of the insulator.
-
Gently place the spark plug boot over the ribs and twist the two pieces back and forth to even out the layer of dielectric grease.
-
-
-
Place the new spark plug firmly in the spark plug socket so that the threaded end sticks out.
-
Apply an even layer of anti-seize compound to the threads of the spark plug.
Regardless of the plug type (Double platinum or Iridium) In the aluminum head Duratec 2.0 motors Ford recommends nickel based anti seize compound rated for 2400 degrees F on the threads. Copper or aluminum based anti seize is not to be used. Only apply a small amount to threads. Also, a blow wand long enough to reach inside the plug hole in the head and compressed air should be used before the new plug is screwed in to remove any rust from old plugs that may have fallen in during removal. Tighten new plugs with a torque wrench to 106 in/lbs or about 8 foot/lbs. Do not overnighten.

-
Place the new spark plug into the cylinder head and tighten it by hand as much as you can.
-
Tighten the spark plugs to 11 ft-lbs with a torque wrench.
106 Inch pounds or about 8 foit/lbs is the Ford torque spec. 11 ft lbs is incorrect

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
Pat
I have 2007 model Ford focus st and the problem I have started when I changed my spark plugs and now there is no power and can only ďrive oņ 40km per hour.

Can you tell me the correct gap on the Plugs for a Ford Focus 2006 model 5 door 16 engine size I know the gap must be spot on
E-mail address is jimdavidson63@icloud.com Thanks
It says in the introduction to this guide that suggested gap is 0.050.
The recommended spark plug gap is 0.050” but I don’t understand why the compatible NGK Platinum plug pre-set gap is 0.040”. Should the gap be adjusted or left as is?
That's the spark plug boot
What if I didn't disconnect the ignition coil electrical connector before I changed the the spark plug, how can I reverse it
