For some reason, Champion and Autolite are recommending a hotter plug than was originally listed for the Stude OHV engines.The new Champion catalogue shows an RH18Y [857] plug instead of the H14Y [91]. The H14Y is still listed in the Champion catalogue if anyone wants to use them. The recommendation of a hotter plug may have something to do with the reformulated gas that many of us are forced to use in our engines. The Champion recommendation for the R engines is RJ12YC [14] which is still the same as the earlier recommendation. Bud
