^ 104's.
How are the 605's burning?
606 might even be the correct plug.
you want to run the hottest plug possible
i know that ^^ the 605's seem to be running a little cold but i also dont have a tune yet. i feel that the 104's might be to cold. when i put the pulley on my car i drove it around the block and it had 0.0 knock so i think i might stick wiht the 605's.
