1. Conventional Spark Plugs: Conventional spark plugs typically have a recommended replacement interval between 30,000 to 50,000 miles (48,000 to 80,000 kilometers).
2. Platinum or Iridium Spark Plugs: Platinum or iridium spark plugs are designed to last longer than conventional spark plugs, with replacement intervals typically ranging from 60,000 to 100,000 miles (97,000 to 161,000 kilometers) or even longer.
3. High-Performance Engines: High-performance engines or vehicles used in demanding conditions may require more frequent spark plug changes, as the spark plugs may wear out more quickly under higher stress and heat.
It's important to note that some factors, such as driving style, fuel quality, and environmental conditions, can affect spark plug wear and life. Regular maintenance and inspection of spark plugs can help ensure optimal engine performance and fuel efficiency. If you experience any issues or symptoms related to spark plugs, such as engine misfires, rough idling, or decreased fuel efficiency, it's best to consult with a mechanic or refer to your vehicle's service manual for specific recommendations.
