The 6 sparkplugs in my jeep wear odd. It has a waste spark system and I don't know if that matters.
It does not matter what brand of plugs I use although autolite were the worst. Cyl 2-4-5 open up the gaps quickly.
The plugs are to be gapped @.035 and yes I gapped them.
Currant ngk plugs have about 7000 miles on them. 2-4-5 were @0.45. 1-3-6 were still
035.
Why would those 3 plugs open the gap up so much so quickly? The plugs do not seem to be worn at all. Just bigger gaps.
As mentioned it's always done this and plug brand does not matter much with the exception of autolite that were .080 on those 3 cyls.
