Spark plug deceision
Anyone using E3 Diamond Fire plugs out there? I have had great results with my I6 4.0L motor in my Jeep. They cut down on idle vibration and seem to smooth out the acceleration.
Haven't installed them yet but have them in hand ready to install if they are any good.
Let me know Thanks

I run a cheap Autolite plug in my modded engine, or you can run regular old Delco Rapidfires. Splurging on the plugs is not really a necessity.
