I went to the DSM, EVO, GTR shoot out last august and looked at 8-9 second cars. Care to know how many where running factory plugs? All of them
Not to travel too far off topic, but short of a window sticker, there is no way to see the "plugs" on these vehicles unless you're the tech inspector taking them apart!
Just sayin.. .. .. That'd be like looking at my bike and telling others what plug I'm running.
Gap matters. New parts can be bad, Attention to detail is the biggest bang per buck as it costs nothing.
