OEM Automotive Spark Plugs

Get the Facts About Spark Plugs

What they do: ignite the mixture of fuel and air in your vehicle's engine.

Why they do this: for combustion -- burning the mix produces the power the engine runs on.

How they work: as part of a process called spark ignition.

How the process goes: the key turns in the ignition lock cylinder, the ignition switch trips, and the car battery, starter motor, starter solenoid, and ignition coil work together to generate electricity. The plugs' leads pick up the charge, combustion occurs, and everything starts running -- the engine pistons, the crankshaft, the alternator, and more.

The symptoms of a bad one: corroded and/or excessively wide leads, wear, breakage, low conductivity, hard starts, and worsening fuel economy. Also, engine misfires, idling roughly, and acceleration problems.

When they should be changed: if you see the signs mentioned above. Alternatively, when you run an engine inspection and its results recommend replacement. Otherwise, before they exceed the mileage limits recommended in your owner's manual. Before ordering new ones, be sure they're genuine.

Why buy genuine OEM spark plugs: your brand designs and builds them to fit your model specifically. That's a fitment guarantee the aftermarket can't always make.

Where to order replacement spark plugs online: from our auto parts store. We carry copper, platinum, and iridium, both regular and extended-life. Just browse our catalog by make, model, and year; it'll make finding what fits go quicker and easier. Buy them now, and we'll ship them out ASAP, directly to your door.
