NGK BR6FS stock # 4323 - gapped at .040
You also have more options with NGK V- power and Racing V- power along with Iridium BR6FIX stock # 2318 gapped .040
Racing V- power R5673-6 stock # 2405 - some people will say R5673-7 that is one heat range colder compared to BR6FS according to the NGK charts.
Standard V - power YR5 but these are one heat range hotter. So really not that recommended unless needing a hotter heat range and want standard V-power plug..
