Well, finally got around to it. Had great weather- low 70s and overcast so it was very pleasant. First time other than oil changes that I’ve had to touch anything other than adding the S&B intake. Realistically, I probably could have left them in with how good they look. Yes, AFAIK these are the plugs the truck rolled off the line in mid 2019 with; I got it with 23k and I’ve never changed them. Plugs are arranged outer to inner from back to front, side respective. Thoughts?
I’d say probably 40k of my 50k has been run with 5 Star Tuning’s 87 Perf-Tow tune, and probably 8-9k with the E30, ~510rwhp tune. I think they held up well, considering the truck frequently sees E15, and obviously E30 for about 11% of the time.
Replaced with NGK Ruthenium HXs.
