How often should the spark plugs be replaced for Golf 6?
2 Answers
Golf 6 spark plugs should be replaced every 54 months. The working principle of spark plugs is to introduce the pulsed high voltage generated by the ignition coil into the combustion chamber, using the electric spark generated by the electrodes to ignite the air-fuel mixture and complete combustion. The Golf 6 is a compact 5-door, 5-seat hatchback with body dimensions of 4199mm in length, 1786mm in width, 1479mm in height, and a wheelbase of 2578mm. The Golf 6 is equipped with a 1.6L naturally aspirated engine, delivering a maximum power of 77 kW and a maximum torque of 155 Nm, paired with a 5-speed manual transmission.
My Golf 6 has been running for over five years, and the spark plugs have been replaced twice. The original manual states to inspect and replace them at 30,000 kilometers, but the actual lifespan depends on the material: nickel alloy ones need replacement at most by 30,000 kilometers, platinum ones can last up to 50,000 kilometers, and iridium ones are the most durable, reaching up to 80,000 kilometers. The first time I replaced them, I waited until 40,000 kilometers, and as a result, the engine shook like it was dancing during cold starts. I recommend not just relying on the mileage; pay attention to whether there's any hesitation during acceleration. A sudden increase in fuel consumption is also a sign. During the last maintenance, severe carbon buildup was found on the ignition coils, a problem caused by the aging spark plugs, which ended up costing me extra money unnecessarily.
