Allow your engine to cool for 3 to 4 hours before changing your spark plugs. They can be extremely hot if you do not allow enough cooling time. On most vehicles, you should replace your spark plug wires at the same time as your spark plugs.
Warnings. 1  Make sure you gap your plugs to the specified gap, unless the plugs say do not gap. 2  Do not try to change the gap of a plug that says do not gap. 3  Putting spark plug wires back on the wrong plugs will cause a poorly running engine, and may make you think you have bigger problems than you do. If you're having trouble locating the spark plugs, look for the black rubbery wires running around the engine. 2  Follow them to the end and you'll find the spark plugs. 3  Check your car's owner manual for the exact location of the spark plugs and the spark plug size you need.
