Champion vs Nippondenso Spark plugs
The plugs at question are Champion and Nippondenso. The Champs are single prong and the Nips are dual prong. Took out the Champs and installed Nips dual prong and truck runs much better. My question is this. The book says to gap the plugs at .043, but the guy at the dealership said NO!, put them at .032. I left them at .043. What should they be at?

You should not use single electrode plugs unless they are iridium plugs.
They should be fine without gapping but when in doubt, owner's manual is correct.
......I visually inspect each plug but never gap them.

I made the mistake of running champions when I first got my 4Runner and it had a horrible misfire. I have been running either Denso or NGK ever since (the double electrode plugs).

I found a post in which someone emailed NGK asking about gapping the dual electrodes and they said not to... Here is the link to the post... https://www.yotatech.com/forums/show...9&postcount=23
Might be just for NGK's... Just leave it as it came...
