Generally speaking you want to use cooler plugs for a higher performance engine. There named cold plugs becausethey have shorter insulatornoses, to expel heat.
It should be in the .45 inch range on a normally aspirated engine and around .29-.35 inch on cars running forced induction. its a good idea to coat the threads with an anti seize compound befor installation.
