A spark plug carries high-voltage current from the ignition system into the combustion chamber and jumps it across the electrode gap to ignite the compressed air-fuel mixture. As plugs wear, the gap widens and the firing surfaces erode, which is why worn plugs are a common contributor to rough idle, misfires, hard starting, and reduced fuel economy.
- Ignition duty: Fires the air-fuel mixture on each combustion cycle to help support normal engine operation.
- Direct-fit replacement: Installs in place of the original plug on the listed applications.
- Signs it may need replacing: Rough idle, misfires, hesitation, or hard starting when the plug is the cause.
Interchange: Manufacturer part number 9605.
