Cold spark plugs for Chevy K1500 have more contact area that works better on modified performance engines and those that produce more heat. Conversely, a hot plug has a smaller contact area. It's critical for all types of plugs to hold up under the pressure and heat of the cylinder and resist developing deposits from fuel additives.
