1. Observe the following service precautions:
   
   Allow the engine to cool before removing the spark plugs. Attempting to remove spark plugs from a hot engine can cause the spark plugs to seize. This can damage the cylinder head threads. Clean the spark plug recess area before removing the spark plug. Failure to do so can result in engine damage due to dirt or foreign material entering the cylinder head, or in contamination of the cylinder head threads. Contaminated threads may prevent proper seating of the new spark plug. Use only the spark plugs specified for use in the vehicle. Do not install spark plugs that are either hotter or colder than those specified for the vehicle. Installing spark plugs of another type can severely damage the engine.
   
2. Turn the ignition OFF .
3. Disconnect the Electronic Ignition (EI) module harness connector.
4. Remove the spark plugs using a 5 / 8 inch spark plug socket.

1. Inspect the gap on the new spark plugs, re-gap the plugs as required. The spark plug gap specification is 42 inch. (1.0 mm).
2. Install the spark plugs and tighten to 15 ft. lbs. (20 Nm).
3. Apply dielectric compound to the spark plug boots and make sure no corrosion is present.
4. Install the ignition coil housing to cam cover and attachment bolts.
5. Tighten the ignition coil housing bolts to 89 inch. lbs. (10 Nm).
6. Connect the EI module harness connector. Push in until a click is heard and pull back to confirm a positive engagement.
