WebRacing Heat Range and Tuning Guide. 12 page guide by Champion Sparking Plug Co. Ltd.'s Competition Department, 1973. Introduction. 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. WebThe spark plug industry has determined that the ideal temperature of a spark plug under operating conditions is between 950*F and 1450*F*. Less than 950* and the chances of a plug “fouling” becomes greater. At the same time a spark plug temperature exceeding 1450* increases the likeliness of pre-ignition and detonation. WebApr 29, 2024 · The ability to “read” a spark plug can be a valuable tuning aid. By closely examining the insulator firing tip color, you can determine a lot about an engine’s overall operating condition.
