The AR33 racing plug style elctrode is a good place to start if you plan to introduce NOS, heaven forbid! Yes it is a cold plug, but you want to start cold and progress towards hot to the optimum. Street plugs and fresh race plugs at the track are probably the way to go for most types of drivers. FE plugs are easy to remove and I don't mind the expense of changing plugs, just don't want to find signs of the plugs taking aluminum, hot plugs/hot engine bay/ less than optimum timing,not enough octane and you got pre-ignition. As loud as these Cobras are you won' hear the pinging and might not feel it. Plan on progressing and experimenting cautiously until you have it all jetted and dialed in.
