What are the benefits of changing spark plugs?

[SanAlexa]

The benefits of changing spark plugs include: ensuring complete combustion of gasoline, thereby achieving optimal power output and reducing fuel consumption. The steps for replacing spark plugs are: 1. Disconnect the high-voltage wire connector, taking care to operate gently and avoid forcefully shaking the spark plug insulator to prevent damage to the spark plug's sealing performance; 2. Loosen the spark plug to be removed, use a thin, soft tube to blow away any dirt around the spark plug to prevent debris from falling into the combustion chamber when the spark plug is removed; 3. Clean the area around the screw, the spark plug electrode, and the sealing gasket to ensure they are clean, dry, and free of oil; 4. Use a socket to align the spark plug with the threaded hole and gently screw it in by hand until about half of the thread length is engaged, then use a torque wrench to tighten it. If resistance is felt during tightening, remove the spark plug to check for proper alignment or any debris in the threads. Do not force it to avoid damaging the threaded hole or the cylinder head; 5. Tighten the spark plug to the specified torque.
