is this fit to mazda6 3.7L v6 2012 ?

Bosch 6728 is the correct spark plug for a 2012 Mazda 6 3.7l v6.

Will these plugs work in a 1984 chevy g20 full size van with a 350 motor?

no use 6712. 6728 are not correct

What is the gap on this ?

I don't know if this helps you, I use it for my Ford f150 pick up and it works great.

Came with damaged packaging

The boxes came very damaged. Looked like they had gotten wet. The plugs worked fine. Not worth the 9.00 each I paid for them.
