Capri is right about explorers connected to the exhaust manifold, i have an explorer intake and i removed the egr valve completely and blocked off the port on the egr spacer, i've heard people say that it wont run right like this, not sure why they think that but it has run fine ever since i pulled it off
are you sure it was the upper that didnt have the egr passage? i thought the lower on mine was the one that didnt, i could be wrong though
