Alright ladies and gents well needless to say i think i overlooked this greatly and never bothered but figured id get everyones opinions. Currently running ngk tr6's with the oem plug gap but from what I've read in the 4.6 mod motor building book that the recommended gap is 0.035 in naturally aspirated set ups. Currently there set at 0.059 If i remember right. Any down side to running the gap this huge is it fine ? I thought i did good until i remembered there a step colder as the old plugs were gapped all over the place with tr6's
