Spark Plug

Category: automotive

A device that delivers electric current from the ignition system to the combustion chamber.

Spark plugs create the "explosion" inside your engine. Over thousands of miles, the electrodes wear down and become coated with carbon. Replacing them restores fuel efficiency, smooth idle, and crisp acceleration.

Common Examples

• Replacing the aged spark plugs resolved the engine hesitation and improved our overall fuel economy by nearly 15%.
• Using the wrong heat range or gap setting for your spark plugs can cause poor engine timing and potentially lead to internal damage.
