Well, I'll give you guys an update on this. Since I pulled these plugs I ran one gas tank of Chevron Techron fuel system cleaner and after that tank was gone I filled up and put Gumout Regane Complete Fuel System Cleaner(clear bottle with gold fluid). I ran the Chevron product because I have personally seen it mentioned on this forum more than any other fuel system product that can be found locally. I ran Gumout because I know many people who do a good deal of track racing and they tried it on their daily driver vehicles and have seen less carbon in the combustion chamber afterwards.
Well the combination of products had cleaned up the tops of the pistons significantly, I can actually see the tops of the pistons in some places while before all I could see was burned on oil and carbon.
The oddball spark plug that this thread was based off of was completely changed as well, I would say that about 75% of the carbon on that plug is now gone and all of the white powdery stuff is completely gone as well.
Since I pulled the plugs I changed them. I went with the same Autolite 3293 plugs because I couldn't find the 'one-step colder than stock' plugs in the NGK's that I was looking for.
I guess it will be another 20k-30k miles(30k is what is recommended, but who knows) and then I'll take another look when they get replaced again. They didn't seem as scorched looking when they came out this time, seemed to look just right and pretty much the same as other plugs I have pulled out. I pulled them today after going on a long 120 mile highway run yesterday.
If you guys want pics of the plugs I will line them up and take a picture, they all look pretty much the same now and are the basic slightly darkened gray plug that we all expect to see coming out of an engine after about 8,000 miles.
Performance wise I didn't expect an improvement at all, didn't get one with acceleration but I do notice a tad difference in the very low(under 1000 rpm)speeds that it seems more powerful as once it gets below idle such as if i'm going in reverse at a slow speed it feels like its got more power for each individual combustion. I don't drive like that though so don't get that impression but I just noticed that as I inched backwards slowly while parallel parking in front of my house trying not to hit the car in front me or behind me.
