• Determine the thread diameter, length (reach), and whether tapered or gasket (flat) seat. • Select gap style.
• Select heat range.

• Inspect plugs and pistons for evidence of detonation, abnormal combustion or excessive temperatures.

Spark Plug Heat Range Tech
range from as low as 500°F to as high as 2,500°F. Manufacturers offer plugs in many heat ranges, from cold through medium hot, to very hot. It is imperative that the plug stay cool enough to prevent pre-ignition or electrode destruc- compression ratio has been altered, a different heat range plug may be required. Many racers rely upon their engine builder for plug heat range recommendations. If a racer is unsure of the correct heat range to use, it is always recom- mended to “stay on the safe side” and use a colder plug. A switch in heat range can change the temperature of the engine. A plug which is too hot can cause pre-ignition and detonation, often resulting in a severely damaged engine.
