There are different types of spark plugs; conventional and platinum. The Conventional Spark Plug typically needs to be replaced every 20,000 to 30,000 miles as they are the most basic and least expensive type. You also have Platinum spark plugs that have a longer lifespan and typically lasts between 60,000 and 100,000 miles before needing replacement.
