#gap tool

[hometowne-auto-repair-and-tire]

New spark plugs were suggested for a Nissan Maxima.

The spark plugs are worn and have too much gap. The gap is 0.055 inches but should be 0.044 inches. 

There needs to be a certain amount of gap between the spark plug and the electrodes. Once they get out of tolerance, usually that means they need to be replaced.
