Hello,
I went to the wrecking yard to hunt down a replacement lower air-box; they had several 4 cylinder Rangers but no 2.9L so I looked at their air-boxes. For the most part, they are the same.
DIFFERENCES:
1) some ½" tube connection coming off the front
2) the air bypass valve (ABV) is mounted to outboard side of the air-box lid.
Why do you suppose they put the 4 cylinders air valve on the air-box lid verse the intake manifold? I want to move mine to the air-box, blank off the manifold port and see what happens ..)
I think that the computer will see the lower temperature and raise the idle, which I do not want but am curios.
