What It Is

Spark plugs create the spark that ignites the air and fuel in each cylinder. They wear out gradually as the electrode erodes.

Why It Matters

Worn plugs cause misfires that damage the catalytic converter, a much more expensive part to replace.

Iridium plugs every 80,000 to 100,000 miles. Copper or platinum plugs every 30,000 to 50,000 miles.
