Genuine Ford Spark Plugs

You're not going to be able to start your car, truck, SUV, or van without ignition. That only comes about once your factory spark plugs have generated the initial flash that kindles the air/fuel mix gathered in the engine.

How Spark Plugs Work

The spark plugs fire an arc of electricity across a gap between two leads. The gaps are calibrated to deliver the optimum sparking that's needed to inflame the mist inside the engine cylinder. Once you have ignition, the pistons pump, the crankshaft turns, and you're ready to go.

How to Spot Failing Spark Plugs

Eventually, even the best spark plugs can go bad. Perhaps the gap between leads has grown too wide to produce an effective flash. Maybe they've grown corroded. Signs of spark plug problems include:

• Engine misfires
• Unsteady engine idling
• You have problems starting the engine
• The Check Engine dash light comes on

Your owner's manual details how long you can expect to drive on one set of spark plugs without replacing them. To avoid engine problems, change out the old ones before they go past their rated kilometrage. Your best choice is always going to be the genuine OEM spark plugs that were produced to work with your model's engine. They are, after all, the only ones that are guaranteed to be compatible.
