Does it matter what plug goes where, I know there is an order, but say I have them in that firing order, but not sure where the first one is suppose to start, Ive been told the cap should have numbers on it and Ive been told it doesnt matter, the cap I have has no numbers on the outside or inside. Just wondering, heres a picture of it
