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.

 

anyone? i know yall running the rx8 plugs . you guys just put them in there no gapping?

 

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

 

I tossed some stock leading RX8 plugs in my Tii with no issues didnt mess with the gap.

 

Thanks guys
