Well that?s easy, its right there on top, inside the black plastic assembly. Just pull it out, remove the filter, stick in a new one. With the hood open, and you are standing there, look down at the right hand side, black plastic container with a large air hose coming out from the left side of it. On the 2.4L engine, you just pull it out towards the left, on the other engines, it's a little different, look at closely, you will see how it just fits in there.
