Just bought some new ac delco plugs for my sunfire and grabbed new ngk wires too . I have never gapped plugs before and can,t locate the gapp for my engine .I have a tool but not sure how to correctly use this tool .Is it very important to gap the plug or do these specific plugs come pre gapped ?..
