Another spark plug question
I know this has been talked about many times here. I did a search here all the way back to 2010 - 2016 about the right plugs for the right heat range but has anything changed since then? I am currently running Motorcraft TT10's and I think I want to bump it up a tad in the heat range per the way I drive my '30 Tudor. The plugs are always black but never fouled up with soot or anything but since I only drive locally at slower speeds and RPM's would a hotter plug clean up the plugs a little? If I do get new plugs I was thinking maybe Champion W18's. By the way I just changed my gap from .032 to .035. I think someone on here said that is acceptable. Tomorrow I will take it for a spin. Thanks, Jim
