I've been told that the covers go on a certain way or they will not fit properly and it is obvious. I know the clips on the one cover goes toward the Intake Manifold but how about the other side? They both have the 0 on them and the one with the clips has the 0 on the clip side. Would the other cover have the 0 go towards the Intake Manifold? When I put them on I don't see a difference one way or the other.
