The Best Automotive Spark Plugs

Refine Results

Spark plugs ignite the mix of gas and air in your engine, in a process called "spark ignition." The process starts when you turn your key in its ignition lock cylinder. Your ignition switch activates, and your car battery, an ignition coil, a starter solenoid, and a starter motor begin working. Together, they generate a small electrical charge, a "spark." The plugs' leads pick it up, ignition occurs, your engine pistons get pumping, and your crankshaft gets turning.

Spark plugs don't last indefinitely, though. Sometimes, their leads rust or widen, and they end up unable to capture sparks as well. If your engine starts to misfire or it fails, it's often a spark plug problem. Broken plugs, however, can seriously damage your engine cylinders. In any of these cases, inspect to determine what's happening, and if necessary, replace your spark plugs. The ones your brand makes for your vehicle are resilient enough to last for millions of ignitions, often for up to 100,000 miles. Just don't let them go past the mileage limits recommended by your owner's manual.
