How often should the spark plugs of a 1.6L New Sagitar be replaced?
2 Answers
Under normal circumstances, the service life of a 1.6L New Sagitar's standard resistor spark plug is 20,000 kilometers, platinum spark plugs last up to 40,000 kilometers, while iridium spark plugs can reach 60,000 to 80,000 kilometers. Actual conditions may vary. Here is relevant information about spark plugs: 1. Introduction: The spark plug is a key component in a car engine's ignition system. Its function is to introduce the high-voltage electricity generated by the ignition coil into the engine cylinder, creating a spark across the electrode gap to ignite the air-fuel mixture. Currently, common types of spark plugs include resistor spark plugs, platinum spark plugs, and iridium spark plugs. 2. How to determine if spark plugs need replacement: Remove the spark plugs and observe the color of deposits, the electrode gap, and whether there is air leakage between the ceramic insulator and metal shell. If the car has difficulty starting when cold, noticeable jerking during driving, idle vibration, or reduced engine acceleration performance, the spark plugs should be inspected promptly.
I drive a 1.6L New Sagitar, mainly for commuting to work. The Volkswagen manual states that spark plugs should be replaced every 30,000 kilometers, but a friend at the 4S shop mentioned that if driving habits are steady, with less traffic congestion and more highway driving, it can be extended to 40,000 kilometers. I replaced the spark plugs at 32,000 kilometers last time, and noticed the engine starts much faster, throttle response became more sensitive, and fuel consumption dropped from around 8L to 7.5L. Worn-out spark plugs can cause delayed ignition, possible idling vibrations, affecting driving comfort and safety. It's recommended to check the electrode gap during routine maintenance; if the gap is too large, they should be replaced immediately. A set of spark plugs costs around a hundred yuan, and replacing them isn't difficult—don't skimp on small expenses at the risk of bigger issues. Regular maintenance also protects the ignition system and prevents engine problems.
