OEM Spark Plugs

What Do Ford And GM Spark Plugs Do?

Your spark plugs help to create the initial flash that ignites the air-and-fuel mixture that powers your engine.

How Do Ford And GM Spark Plugs Work?

The spark plugs shoot an arc of electricity across a gap between the plug's electrodes. Those gaps are precisely calibrated to provide the optimized sparking needed to burn the mix in the engine's combustion chamber.

However, your model may boast a diesel engine, rather than gas. If that's the case, it relies upon glow plugs rather than spark plugs. Glow plugs feature a heating element in their tip, with the element igniting the mist of fuel that's sprayed into the engine cylinders.

What Happens When Spark Plugs Fail?

If your spark plugs grow corroded over time, or their gaps widen too far, you'll find that it's harder to start your vehicle, or that your engine idles rougher than normal. Your engine may even start to misfire, or you may start to experience a significant lag in acceleration. Worsening fuel economy is another costly example.

Why Buy Genuine Ford and GM Spark Plugs?

That's an easy question to answer. Both Ford and GM make their parts exclusively for their models -- and that goes for their parts divisions Motorcraft and ACDelco, respectively, as well. That means you're getting the OE and OE alternative parts that offer the precise fit, top quality, and outstanding performance you want. Generic parts can't, and won't, make that same claim.
