Looking around at the various offerings for spark plugs in my PA32R and there seems to be quite a few (at least according to the Tempest & Champion application guides). Is there a best offering and what exactly are the differences? I must admit I know less than I probably should about these things. Always thought they were a very simple thing. For example, the Champion guide says that RHM38E, REM38E, RHM38S, or REM38S will work, but that REM38E is the most commonly used. Why is that? Conversely, in the Tempest guide, it says URHB32E, URHB37E, UREB36S, URHB32S, or URHB36S will work. I honestly thought the models would be closer. There IS a UREM38E model from Tempest, but their guide doesn't indicate that it's appropriate for my engine.
