Spark plug replacement requires a spark plug socket that fits onto a ratchet, lined with a rubber grommet to protect the porcelain insulator of the spark plug and to hold the plug while you insert it into the spark plug hole. A wire-type feeler gauge is needed to check and adjust the spark plug gap and a torque wrench to tighten the new plugs to the specified torque. On engines equipped with a V-bank cover, remove the three 5mm cap nuts and detach the cover for access. If replacing the plugs, purchase the new plugs, adjust them to the proper gap and then replace each plug one at a time. The manufacturer specifies that only platinum or iridium-tipped spark plugs be used on these models. Inspect each of the new plugs for defects and check the electrode gaps. On V6 engines, remove the retaining bolt, disconnect the electrical connector and detach the individual coils to reach the front spark plugs. Work on one spark plug at a time, remove the wire and boot from one spark plug. If compressed air is available, blow any dirt or foreign material away from the spark plug area before proceeding. Remove the spark plug and apply a small amount of anti-seize compound to the spark plug threads. Attach the plug wire to the new spark plug, using a twisting motion on the boot until it is firmly seated on the end of the spark plug. Follow the above procedure for the remaining spark plugs, replacing them one at a time to prevent mixing up the spark plug wires.

Use a twisting motion on the boot until it is firmly seated on the end of the spark plug.

Remove the engine cover(s) and disconnect any interfering hoses or components. Use compressed air or a bicycle pump to remove dirt or foreign material.

Remove the wire and boot, then unscrew the spark plug.
