Spark plug replacement requires a spark plug socket, extension, and ratchet. The socket is lined with a rubber grommet to protect the porcelain insulator of the spark plug and hold it in place during insertion. A wire-type feeler gauge is needed to check and adjust the spark plug gap, and a torque wrench is necessary to tighten the new plugs to the specified torque. When replacing the plugs, it is important to purchase the correct ones for your specific vehicle. Inspect the new plugs for defects, such as cracks in the porcelain insulator, and check the electrode gaps using a wire gauge. If the gap is incorrect, adjust it using the notched adjuster on the feeler gauge. Be cautious when handling platinum or iridium spark plugs, as they are pre-gapped and should not be adjusted. Before removing the plugs, blow away any dirt or foreign material with compressed air. The ignition coils are mounted directly over each spark plug and must be removed to access the plugs. Use a socket with a long extension to unscrew the spark plugs. Compare each old spark plug with the provided chart to assess the engine's overall running condition. Prior to installation, apply anti-seize compound to the plug threads to prevent cross-threading. Use a short piece of rubber hose to help align the plug with the plug hole and prevent thread damage. Attach the coil to the new spark plug and tighten the mounting bolt securely. Repeat this process for the remaining spark plugs, replacing them one at a time to avoid mixing up the ignition coils.
