Just purchased 6 Bosch Platinum plugs for my '90 4.0l. I have used them before, and currently have them in, but its time to change them. The plugs I got are Bosch 4202. I have always gapped them to .035, the factory spec, but now I'm hearing that one does not need to gap platinum plugs. The gap on these Bosch plugs is larger than factory spec. Do I gap to spec or leave them alone. Any comments?
