Spark Plugs

Spark plugs are insulated plugs that sit atop each cylinder in your engine. They create the spark that ignites the air/fuel mixture in your combustion chambers. Many stock spark plugs need replacing as early as 30,000 miles, but quality iridium or platinum-tipped ones can last as high as 120,000 miles. If your fuel economy starts to drop, the engine misfires, or if the engine has trouble starting, there may be an issue. To ensure your spark plugs last as long as possible, it's important to buy OEM parts straight from our site.
