What is the true tourque for your spark plugs
I have discuss this with other 8 owners,
Mazda says to tighten by hand untill you feel resistance and a half turn and the plug will be tourqed,
others say to tighten by socket until plug will not turn anymore (im sure this will work out to be an crazy amount of FPT,
and others say you tighten by hand a make a two full rotation,
What is the CORRECT tourque in your opinion?

I don't recall offhand whether the half turn is the right value for our plugs, but that kind of spec applies to a new crush washer. If you're putting a used plug back in and using the same washer, that won't get you there. Use a torque spec, like Edzride says.
If you have a car that uses tapered seat plugs without a washer, then "hand tight plus 1/8 (or whatever) turn more" always works.
