Spark Plug Parts For My Ford

Without the spark plugs, your Ford vehicle wouldn't be able to start. That's because spark plugs are responsible for igniting the fuel and air mixture inside your engine, in a process known as spark ignition.

How Spark Plugs Work

It all starts when you either turn the key in the ignition cylinder or press the "Start" button. That activates the ignition switch, causing your battery, starter motor, starter solenoid, and ignition coil to produce an electric charge. The spark plugs capture that charge in their leads and shoot an arc of electricity across a gap. That leads to the combustion your engine needs to get the pistons pumping and the crankshaft rotating.

Spark plugs don't last forever, though. The leads can widen too far or get rusty, weakening their ability to conduct the electricity. The plugs can corrode, or even break. If they should break, that's serious. That can cause damage to the engine cylinders.

How to Identify Falling Spark Plugs

Signs of trouble include:

• Misfiring engine
• Difficulty starting your vehicle
• Rough engine idling
• "Check Engine" dash light comes on
