A hot plug is a better heat insulator and has a smaller contact area at the tip, while cold plugs have larger tips for more contact so they run cooler. That tip withstands the heat inside the cylinder, and the best Ford Thunderbird spark plug prevents knocking and deposits in your engine. The insulated passageway allows high voltage to travel through to the engine block of your car. Not only does AutoZone carry Thunderbird performance spark plugs, but we also offer benefits such as free engine diagnostic testing and battery charging when you visit your local store.
