Review on Premium Manifold Assembly Mountaineer 2002 2005 by Sean Xayamonty

Pulled the original part and compared it to this - the part of the header that goes down for air distribution is not as deep as the OEM part. This leads to a drop in performance. Dissatisfied. Unfortunately, it looks like the ONLY option is a $400+ OEM part from Ford. This unit also comes with non-standard equipment such that a pair of clamps and rails cannot be replaced and there is no ground wire for fuel rod assembly. can't be attached to the stud it was on so you'll have to come up with something to make it work. It's downright *dangerous* if someone just leaves it unplugged or plugs it somewhere else that won't ground the fuel rail.
