      A:

      No, this Autolite Spark Plug - part# XP5405 is not pre gapped. Gap new plugs as recommended in your owner's manual or a Spark Plug Catalog. Use a feeler gauge to measure the gap between the center and ground electrode. The gauge should pass through snugly but easily. If it's too loose or too tight, reset the gap.
