What is how often to change spark plugs?

Spark plugs play a crucial role in the combustion process of an engine. Replacing them at the recommended intervals is essential for maintaining optimal engine performance and fuel efficiency.

• General Recommendations: Typically, spark plugs should be replaced every 30,000 to 90,000 miles, depending on the type of spark plug and the vehicle's manufacturer recommendations. Consult your vehicle's owner's manual for the specific interval for your make and model.
• Types of Spark Plugs: Different types of spark plugs have varying lifespans.
  • Copper Spark Plugs: These are the least expensive and have the shortest lifespan, generally around 30,000 miles. See: Copper%20Spark%20Plugs
  • Platinum Spark Plugs: Last longer than copper plugs, typically around 60,000 miles. See: Platinum%20Spark%20Plugs
  • Iridium Spark Plugs: Offer the longest lifespan, often exceeding 90,000 miles or more. See: Iridium%20Spark%20Plugs
• Symptoms of Worn Spark Plugs: Keep an eye out for these signs:
  • Reduced fuel efficiency.
  • Difficulty starting the engine.
  • Engine misfires.
  • Rough idling.
  • Lack of acceleration.
• Factors Affecting Spark Plug Life: Several factors can influence how long spark plugs last, including:
  • Driving habits (aggressive driving shortens lifespan).
  • Engine condition (oil leaks or other issues).
  • Fuel quality.
  • Vehicle's operating conditions.
• Ignoring Replacement: Delaying spark plug replacement can lead to:
  • Decreased fuel economy.
  • Reduced engine performance.
  • Potential damage to the catalytic converter or ignition coils.
