what is the proper gap for theese plugs

used them as they came from the box pre gapped at .40 2004 trailblazer . found some extra ponys after putting them in great plugs !!!!

On the top it says in green this fits my Trailblazer and on the bottom it says vehicle service type motorcycle?

I bought this item sometime November of last year and had my mechanic install all six (6) of them on my 04 chevy trailblazer. And upto this day my rig has been running smoothly without any problems. Can’t go wrong with ACDelco.

Will these fit 2011 V6 Camaro
