How Often Should the Original Spark Plugs on a Golf Be Replaced?

[VanClayton]

Golf original spark plugs should be replaced every 45,000 kilometers or 54 months. Steps for removing spark plugs: 1. Cool the engine and clean the ignition coils and surrounding areas of dust and oil stains; 2. Disconnect the wiring harness plug and use a socket wrench to loosen the bolts securing the ignition coils; 3. Remove the ignition coils and use a socket wrench to loosen and extract the spark plugs. Symptoms of damaged spark plugs: 1. Difficulty starting the engine; 2. Reduced power; 3. Excessive exhaust emissions; 4. Increased fuel consumption. The primary function of spark plugs is to conduct high-voltage electricity from the ignition coil into the engine cylinder, generating a spark across the electrode gap to ignite the air-fuel mixture, enabling the engine to perform work.
