OEM Lincoln Spark Plugs

You can't start your Lincoln vehicle unless you have ignition. That only happens when your spark plugs produce the initial flash of electricity that inflames the air-and-fuel mixture in the engine's combustion chamber.

How Spark Plugs Work

That flash is generated when the spark plugs shoot an arc of electricity across the gap between two leads. Those gaps are precisely calibrated in order to deliver the optimal sparking required to fire the mist inside the engine cylinder. Once you have ignition, your pistons pump, the crankshaft rotates, and you have the power to head out on the road.

How to Identify Failing Spark Plugs

Over time, the gaps could have widened too far to produce a sufficient spark, or your spark plugs may be corroded. Check them if you notice any of these signs:

• The engine misfires
• Uneven idling
• You have trouble starting your vehicle
• The "Check Engine" light comes on

Your owner's manual will tell you how long you can expect to drive on one set of spark plugs without changing them. Replacing your old ones before they go past their rated mileage helps prevent engine problems. Your best choice is always going to be the genuine OEM spark plugs that are guaranteed to be compatible with your model's engine.
