Not Ranked
Ron,
The parts guy at the local shop is pushing the Autolite AP45 plug, which is their regular platinum plug, (also happens to be the one he had in stock).
When I compared the plugs, the Autolite seemed to be a little taller from the shoulder to the top of the electrode, which is a concern; I'm wondering about the temperature range... Autolite doesn't seem to offer any - just one plug/application.
Thanks,
Dan
