Default trying to read spark plugs? this might help

I found this link and its a pretty good site to read up on reading spark plugs. If you dont know what reading spark plugs is, its when you take a plug out after running the motor at WOT and you can tell how its running by the way the plug looks and whats on it. It can give you an idea if the motor is rich,lean,detonating,etc.... its a cool peice of knowledge to have and i use it to read my plugs on my car after a hrd nitrous run to make sure things are good.

Thumbs up

This should be a sticky. I found it very informative. I learned a little more than I knew about plugs and I think it would be very helpful for people that are running FI or just wanna check theyre plugs.....
