The higher the heat range number, the more capable the spark plug is to withstanding heat, thereby it is a colder plug (meaning it remains cooler, it will not heat up as much). Autolite Racing spark plugs feature a cut back ground electrode, anti-corrosive nickel plating, and large ground electrode for better heat transfer. Generally speaking a hotter plug is better for short trips where the engine barely gets warmed up or a high mileage engine that may foul the plugs more easily. However, according to an Autolite reference chart, Autolite 86 has the same heat range as 2244 and Autolite 303 is a hotter plug than 2974. 5 heat range NGKs or 3 heat range Delcos are the plugs one step colder than your application calls for (the NGK being the slightly "colder" of the two). With modern sophisticated engines, new ceramics and superior alloys for spark plugs, the job of selecting a plug for a specific engine has become more critical. In order for the electricity to travel to the electrode and jump the gap toward the engine block, the spark plug needs an insulated passageway. Does Accel go from low number to high number to indicate heat ranges on spark plugs? Meaning, is 576S a hotter plug than a 276S? I think I may need to change the heat range on my plugs, but can't find any information out there about how they indicated heat range on the plug.
