Скачать или смотреть All About Spark Plugs Lifespan

Spark plugs are small but vital components that ignite the air-fuel mixture inside your engine, and their lifespan depends on the material, driving conditions, and maintenance practices. Copper plugs usually last 20,000–30,000 miles, platinum plugs about 50,000–60,000, and iridium plugs 80,000–100,000, though real-world use often shortens these intervals. Factors such as short trips, aggressive driving, poor fuel quality, extreme climates, and lack of regular maintenance can all reduce spark plug life. Warning signs of wear include hard starts, misfires, poor fuel economy, loss of power, or a Check Engine Light. While manufacturers may claim up to 120,000 miles for some plugs, mechanics typically recommend inspection every 30,000–50,000 miles and earlier replacement if performance drops. Common myths—like plugs lasting the lifetime of the car or boosting horsepower simply by switching materials—are misleading; in reality, timely inspection and replacement are essential. By using quality fuel, keeping filters clean, and maintaining your vehicle, you can extend spark plug life and avoid costly engine issues.
