Finally found the Autolite 3923 plugs after ck'g Autozone and O'reillys at Pep Boys.
Got the double platinum for longer life.
Question is on the gap. With the stock plugs, dual prong it's only .031, but the Autolites are about .044 out of the box. For you guys who have installed these, did you leave that gap or change it?
Tks.
