Correct spark plug gap?

[AutoEuphoria]

I've read 0.028" on this forum, but a vendor says 0.032"

Anyone know what is the correct gap for a set of step-colder plugs (if that matters) for the MS3?

.32 is the correct gap
i double checked with my mazda dealer

I think .028 is for non-turbo.

cobb recommends .026-.028.. I just use the preset gap for the densos 1 step colder because i didnt want to damage them regapping them. & they work just fine out of the box..

STOCK gap is 0.032"

If you're running step-colder plugs, you should be running 0.026-0.028".

Yep, what he ^ said.
