Spark plugs gap

[JF1957]

Is the gap on platinum plugs for a 5.7 L is still .60 likes originals ones ?

Thanks

Go by the tune up/emissions sticker under the hood.

If it's a MPI 5.7 then yes, it's probably .060". However, following the emissions sticker is the best way to go.

 

Oh yeah, and every set of Bosch plugs I've ever used has turned out to be junk. I would recommend ACs or Autolites over them.

If you're using the +2's or +4's the gap is pre-set so you don't change it.
