Spark plugs are installed in your engine, and generally changing them out is a simple task. When spark plugs begin to wear out, your engine can misfire, stall and have trouble starting. If you have spark plug problems, look for replacements from popular brands such as NGK, DENSO, Motorcraft, Autolite or ACDelco.
Consider replacing your spark plug wires or boots when changing out your spark plugs.

How long do spark plugs normally last?
Your owner's manual should tell you how often your spark plugs should last. Depending on your model and the type of spark plug, the replacement interval could range anywhere between 30,000 to 120,000 miles.
What causes spark plugs to wear out early?
Each time your spark plug fires, the electrical arc generated wears a tiny amount of metal away from your plug's electrode. Normal use will gradually wear your electrode down to the point where more electricity is needed to trigger a spark, until eventually it can't arc at all. In addition to this wear from normal use, spark plugs can also get worn down by overheating damage, oil contamination, and carbon buildup.
