Iridium NGK plugs
Sorry I am sure this has been answered. It has been a little while since I ordered new plugs, and it looks like the part# has changed. Are the NGK colder 1 iridium now "LFR6AIX-11"? I think they used the NGKLFR6A-11. I did a search, and just want to confirm my findings to be safe. What you guys gapping them at? .032 or so? Thanks.

only the AIX plugs are iridiums (NGK# 6619). You have coppers (NGK# 3672). Hope you didnt pay iridium prices.
There is no reason to touch the gap unless you have spark blowout from high boost. Bigger gap, better spark, better combustion
the normal LFR6a (without the -11),NGK #6668 are pregapped to 0.035". Not sure why everyone gets the -11(NGK # 3672) and then regaps when NGK sells the proper ones.
