rx8 plugs in 13b rx7 question

Noticed people saying you can use rx8 leading plugs for better spark and longer plug life . Was going to order 2 RE7CL for leading . Couldn't find any info on gap.

Do I need to gap these to a specific gap for the my FC . Its NA stock port engine. Stock coils. Thanks guys.

they come gapped, and with a little blurb about how gapping/cleaning them can damage the coatings.
