Now that Spring has finally arrived where I live, I finally got a chance to check out my plugs (along with a good "detailing" under the hood).
I only have 6,000 miles on my truck but the plugs look great ... nice light tan. I checked my gap and all were around .034. I did close them up to slighly under .030. The truck was running good before ... but I wasn't that far off.
She does like the tighter gap. And she rewarded me with a nice burn out when I stomped on it while rolling 20 mph. Even the wife bitched at me for that one.
