Original Ford Spark Plugs

Frequently Asked Questions

What Do Spark Plugs Do?

Ignite the mixture of oxygen and fuel a vehicle's engine needs to burn to generate the power it runs on. No engine would even start, let alone run, without them.

How Does a Spark Plug Work?

The process, "spark ignition," works as follows. First, your key turns in its ignition lock cylinder. Then, an ignition switch activates. From there, the car battery, plus a starter motor, a starter solenoid, and an ignition coil, begin generating electricity. The charge then travels to the plugs' leads; they capture it, and combustion occurs. The engine's pistons pump, the crankshaft turns, your vehicle starts up and, with help from its alternator, stays running.

What are the Signs Spark Plugs are Going Bad?

• Corroded or excessively widened leads
• Worsening electrical conductivity
• Hard starts
• Reduced fuel efficiency
• Engine misfires
• Idling roughly
• Trouble accelerating

Physical weakening and breakage, however, is a worst-case scenario. It usually results in severe and expensive engine cylinder damage.

If you see any such symptoms, run an engine inspection, and replace any spark plugs at issue. Otherwise, change them before they reach their mileage limits.
