Spark Plug: Application and ID

Spark Plug Type AWSF-32PP (a)

(a) Three different styles of platinum-enhanced spark plugs are produced for the 4.6L-(2V) engine. Each plug has a different part number, and use.
^ AWSF-32P spark plugs have a platinum-enhanced center electrode and are used in cylinders 5, 6, 7 and 8.
^ AWSF-32PG spark plugs have a platinum-enhanced ground (side) electrode, and are used in cylinders 1, 2, 3 and 4.
^ If any spark plug is removed and re-installed, it MUST be installed in the same cylinder from which it was removed. If any spark plug is replaced, use only spark plugs with part number AWSF-32PP as listed on the vehicle emission calibration identification label. This replacement spark plug has double platinum enhancement on both the center and ground electrode and may be used in all eight cylinders.
