Caution: When replacing spark plugs, it is recommended to also check the high-voltage wires.
Tools needed to replace spark plugs
1. Deep nozzle
2. Torque wrench
3. Ratchet wrench
4. Extension cord
5. Wire sensor
1. Prepare the necessary tools to replace spark plugs.
2. Using a wire gauge, check the spark gap of the new spark plugs.
3. Adjust the gap if necessary by bending the side electrode.
4. Disconnect the wires from the spark plugs. Use compressed air to clean the area around the spark plugs and remove the spark plugs using a deep socket and extension.
5. Before installing new spark plugs, lubricate their threads with an anti-corrosion compound.
6. Screw the spark plugs into place, using a piece of rubber hose as a universal joint to avoid damaging the threads. Tighten the spark plugs to the specified torque.
7. Connect the high voltage wires.
