    just did my first plug change (currently have 33K on the truck). I think the plugs look good. do you agree? Also, should I be concerned about the dark color on the threads? What is this? Thanks.

    Hard to tell gaps from a photo, but they are on mileage to be changed.
    That been said - Don't see any issues with those plugs from those photos...

    if i had to guess, i bet those gaps are wide. they look pretty good besides that.

    seems the gap is wider than that electrode probe thing.

    I would agree-But on the order of size those gaps are spec'd to...I don't want to guess

    The gaps did open a bit .. they were all between .046 and .052 with the NGK's being worse than the Denso

    Really? You 'saw' a gap increase of 0.020" with your bare eyes from a small photograph? :confused:

    Apparently not as much as you guess at things unable to be seen by the human eye. Way to 'guess' at something that happens with all used plugs by the end of their service life captain obvious. Don't get snarky with me when you're the one making useless posts based off of absolutely nothing you gained from looking at the picture to try to make yourself look cool. What's next? Someone posts a picture of their used motor oil and you 'guess' that there's microscopic metal particulate suspended in that oil? What else can you share with us Nostradamus?

    Hey Great Write Up! Thanks. I was able to do it in a little less than 2 hours. I'm pretty competent and able but I do get paranoid a little. That's my baby. I was wonder, how long would it take to realize if I did something wrong, ie, cross thread the plugs, etc.... It fired right up and sounded great. I just don't want something to come along later and bite me in the butt. I figure if it started and ran then it's all good. Thanks again

    Just did mine, the write up definitely helped. What is really scary is I had the Denso in 2-4-6 and the NGK in 1-3-5. The gaps in the old plugs were:
    1 - .58 2 - .50
    3 - .58 4 - .50
    5 - .57 6 - .52
    Was getting 20.5 avg mpg, so it will be interesting to see if it gets better.
