    Does it give better performance if u chose a brand. I know there's the premium that has 4 pieces around the spark. Is it better than the one piece?

    Stock is ac delco?

    i see you have headers, with stock pulley you can get away with stock range or 1 colder, when you drop pulleys switch plugs to 1 or 2 ranges colder than stock
