Hey all. I've searched around the internet, and many forums regarding plug reading and have found that there are quite a few different ideas on what a good looking plug is and what is not. I know the obvious white is lean, black is rich and toasty brown is just right. What I'm a bit confused by is where exactly on the plug I should be seeing that colour? I did a couple plug chops today at 1/4 throttle, 1/2 throttle and WOT. I didn't get time today to grab brand new plugs to do the testing, but I figured it was still worth checking and seeing to if nothing else, get a general idea. I did notice some subtle differences at the different intervals, but for the most part they all looked fairly similar.
Here are the clearest photos of the most extreme spread I had in the runs that I took. My hope is that someone here with more experience can tell me what these plugs would indicate to them about the conditions it was pulled at.
