Yes I know they are 100k plugs, but Iwant to change them anyway, going for a tune soon. The supposed OE plug is fxe24hr11, NGK does suggest a 7 heat range which is a 22 denso...which is the old HR plug. I can get the fxe22 with ease, anyone see an issue, obviously I am NA.
Nissan see confused as well! (I checked multiple sources)
