Even if you are using pre-gapped spark plugs, it is a good idea to check the gap before installing your new plugs.

Insert the thinnest portion of a spark plug gap gauge between the center electrode and the ground electrode of the spark plug.

While holding the gauge between the spark plug gap, rotate it until it gently wedges itself into the gap.

The distance of the spark plug gap can now be read off the gauge. The factory spec for this vehicle is anywhere from .039 to .043 inches.
