Original Ford Spark Plugs

Refine Results

Without your spark plugs, ignition doesn't take place. That’s because the spark plugs create ignition when they kindle the mixture of fuel and oxygen inside the engine.

How Spark Plugs Work

That happens when the spark plugs fire an arc of electricity across the gap between their leads. The gap is precisely calibrated to produce the ideal spark needed for ignition. Once combustion occurs, your pistons begin pumping and you're ready to head out on the road.

Spark plugs can eventually weaken, leading to engine trouble. Whether that loss of fire is due to corrosion or the gap between leads growing too wide, you'll want to replace your plugs as soon as possible.

How to Recognize Problematic Spark Plugs

Signs of failing spark plugs include:

  • The engine misfires
  • You have trouble starting your vehicle
  • Your engine idles rougher than normal
  • The "Check Engine" dashboard light comes on
