Comments about Autolite Copper Spark Plug:

Pretty much all plugs bought new will have to have the gap on the plug set to the specified range outlined in the shop / repair manual. Not really a downside to the part, Just make sure you set the gap to the requirement for your car or truck. Autolite continues to make some of the best parts on the market. AC Delco parts work the same for more money. Champion plugs also have a good history with me.
