How often should spark plugs with 'T' be replaced?
2 Answers
Regular spark plugs need to be replaced every 30,000 kilometers, platinum spark plugs around 60,000 kilometers, and iridium spark plugs around 80,000 kilometers. Common spark plug failure classifications: Common spark plug failures can be categorized into two types: severe spark plug erosion and spark plug deposits. When the car owner finds scars or damage at the top of the spark plug, or the electrode shows signs of melting or erosion, it indicates that the spark plug is already damaged and should be replaced. During the replacement process, the owner can first check the symptoms of spark plug erosion and changes in color. Effects of not replacing spark plugs: Significant increase in fuel consumption. Reduced engine starting capability. Insufficient power. Vehicle jerking during driving. Unstable engine idle. Spark plug electrode detachment damaging the engine. Vehicle exhaust emissions not meeting standards.
As a guy who's been driving for over 20 years and fixes everything myself, I often encounter spark plug issues. When it comes to 'turbocharged' spark plugs, if you're referring to those high-performance ones like platinum or iridium, they're more durable and generally recommended to be replaced every 60,000 to 100,000 kilometers, depending on your car's condition and manual. In my experience with various cars, when spark plugs age, the engine misfires, struggles to start, and becomes noticeably fuel-thirsty—I've spent dozens more on fuel for short trips. Driving habits matter too; if you frequently drive on highways or off-road, you might need to check them at 50,000 km, while city stop-and-go traffic can stretch it to 70,000 km. Remember, if you hear sputtering during startup or notice sluggish acceleration, that's your cue. Delaying replacement can damage coils or other parts, leading to costly repairs. That's why I pop the hood every six months for a quick check—it saves hassle and money.
