What is the spark plug heat range, and why is it important?
What will be an ideal response?
The heat range of a spark plug is its ability to dissipate heat from the combustion chamber to the cylinder head. It is important to maintain the spark plug temperature between 842°F and 1652°F (450°C and 900°C). If the spark plug burns hotter than the desired range, the electrode could burn, and pre-ignition, detonation, and possible engine damage could result. If the spark plug burns colder than the desired range, the electrode will not be able to self-clean, which will lead to misfiring and poor performance.
