|TSV said: (quoted from post at 14:18:23 11/09/12) What is the hottest sparkplug available for A John Deere LA Tractor?|
It seems as though many people find the Autolite 437 as the best plug for that size. I can not say that it is "hottest" in that size/reach, but it is hotter than a 216. And another alternative would be a NGK B4L I believe. It isn't possible to compare heat-range to heat-range between brands however. So I don't know if it is hotter or not than the 437.
