What I found:
3 Plugs were NGK U-Groove Copper Core plugs (Cylinders 1,2,5 and 6) 1 Plug was a Nippon Denso Platinum, probably from 1st plug change, cylinder 3, directly below the intake. 1 plug was a N-D Copper Core, cylinder #4Interesting. It looks like the last plug change was just done to the cylinders that could be reached without removing anything. The one before probably replaced 1,2,4,5 and 6. The Platimun may have been OEM...
Max Spec is .080". Most of them were .080, #3 was .083, and #4 was .075 Spec is .043"
Hopefully, this is why the car failed Emissions last year...
