    Spark plug gap .052" to .056" gap AWSF-22W is the Ford number for the spark plug. Remove the ignition coils over each spark plug to gain access to the plugs. Labor time shows 3 hours to replace the plugs (I haven't done the job myself but have to do it on my brother in laws Expedition soon). Theses plugs on this engine do get "stuck" in the head so use caution and patience removing the spark plugs. Alldata do not give much information regarding removing the spark plugs perhaps Mitchell or some other automotive information system may have more detailed information.
