How Often Should Spark Plugs Be Replaced?
The frequency with which spark plugs need to be replaced depends on the type of spark plugs you have and how you drive your car. Conventional spark plugs typically need to be replaced every 30,000 to 50,000 miles, while platinum and iridium spark plugs can last for up to 100,000 miles or more.
