I had an aftermarket air filter and wanted a stock one. I got this used and installed it but have a couple questions. The air intake horn points right at the fan shroud. Does that look right? The way the alignment notches are designed it can only go on the box one way so it’s pointed the way it was designed but it looks wrong. Also does anyone know what is supposed to be attached to this nipple on the cover? I taped it up for now. The valve cover vents into the tube going to the intake so that’s not it. Thanks.
The "nipple" on the air box is for the ccv tube. The design was changed after 2004 and the breather tube was moved from the intake tube to the air box. Your air box cover is from a later model. As long as your seal it well it shouldn't cause you a problem.
If you rotate the "trumpet" as it is called enough to unlock it and pull it out, that you can reinsert it in a different position and lock it so it points upward as it is supposed to. The pic in post #4 shows the trumpet in the correct position.
