Autolite 85's are an extended reach plug that match the OEM Champion R/RJ
8/10(obs)/12 Y/YC with a heat range equivalent to the RJ12YC. Autolite 303's
are not extended reach, and are mis-spec'd in the Autolite application info.
There are some anecdotal reports of engines(392's IIRC) that ping with 85's
but not with 303's, I suspect that those engines have other issues that the
303's 'tune around'.
