REMOVAL
1. Disconnect ignition wires from spark plugs.
2. Loosen spark plugs 1/4 turn and remove any dirt or foreign material from spark plug areas of cylinder heads with compressed air.
3. Remove spark plugs.

NOTE: Three different styles of platinum-enhanced spark plugs are produced. Each spark plug has a different part number and use.

- AWSF-44E spark plugs have a platinum-enhanced center electrode and are used in cylinders 4, 5 and 6.
- AWSF-44EG spark plugs have a platinum-enhanced ground (side) electrode and are used in cylinders 1, 2 and 3.
- 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-44EE as listed on the vehicle emission control information label. This replacement spark plug has double-platinum enhancement on both the center and ground electrode and may be used in all six cylinders.

4. Check and adjust spark plug gap.

NOTE: Refer to the Spark Plug Inspection Chart to determine the condition of spark plugs.

INSTALLATION
1. Follow removal procedure in reverse order.
