The colors of our trucks/trailers are the same but reversed. LOL.
BTW, I changed my plugs at 126,000. No major problems. The idle was better and the fuel mileage increased a little bit.
I'll be changing the O2 sensors next week and I bet putting in the new ones will increase the fuel mileage more than the changing the plugs did. The downside is that I suspect removing both upstream sensors is going to be more difficult than removing the 10 plugs.
