I would always double check the gaps 0.7-0.8mm is correct.

Ok, read a few topics where it says about not adjusting platinum tipped plugs? Also my mate has been told by mapper to gap them to 0.6 for 1993 wrx.

0.65 to 0.7 mm and never trust they are pre gapped as they are always over gapped. Use a feeler blade gently don't force it in the gap and you won't damage the platinum tip.
