I just got a ls1 the week, and am going to change the plugs tommarow. I bought Tr6's, so what I need to know is what do I gap these plugs at. I am planning on spraying this car in the near future. The car is bone stock now, but I am going to order full exhaust, underdrive pulley, and a ram-air kit next week. I am going to order a nitrous kit soon after, and a ls6 intake, and a cam might follow. So if you guys can tell me what you gap your plugs at, I would appreciate it. I did a search, and couldn't find what I was looking for, so if somebody has a link to another thread, please post that.
