Spark Plug Recommendation......
I need to "settle" in on a spark plug since we can't currently run the adapters. Has anyone had luck with a particular brand and heat range? I ran the 137 Accels and the Autolite 3933 (I think that's right) but didnt see any difference. I was having some oiling issues at that time, which may have hampered the "testing".
Any help is greatly appreciated......
See you all at INDY!!!!!!
