2 Answers
The X-Trail has 4 spark plugs. What are spark plugs composed of: Spark plugs mainly consist of terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. What types of spark plugs are there: Main types of spark plugs include: standard spark plugs, extended insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. Replacement cycle for spark plugs: Under normal maintenance conditions, replacement is recommended at 40,000 to 60,000 kilometers, but this may vary depending on the brand and engine. It is advisable to refer to the user manual. Platinum spark plugs should be replaced at 40,000 km, ordinary nickel alloy spark plugs at 20,000 km, and iridium spark plugs at 60,000-80,000 km.
The X-Trail generally refers to the gasoline version, which has four spark plugs because the engine typically uses a four-cylinder design, with one spark plug per cylinder. This is crucial, as spark plugs are the core components of engine ignition. If they are old or damaged, the car may start sluggishly or even fail to start, and fuel consumption may skyrocket. I've driven this car for several years, and according to the manual's recommendation, the spark plugs should be inspected every 30,000 to 40,000 kilometers. When replacing them, it's best to choose OEM or high-quality brands, and avoid over-tightening during installation to prevent damaging the threads. Daily driving habits also affect their lifespan—frequent short trips with constant stops and starts can lead to carbon buildup, shortening the spark plugs' service life. Regular maintenance saves money and ensures peace of mind, so don't wait until a breakdown to regret neglecting it.
