Re: Autolite Spark Plugs
To make a head puller, I need to remove the innards from spark plugs so that I can tap them for all thread.
Removing the innards from Champion plugs is relatively easy while the Autolite 216 plugs are darn near impossible. They are just too well made.
Whether that makes a difference to plug performance in normal use I don't know but I suspect that the Autolite plugs will last longer.
