The ford 4.0 OHV engine was used for quite a few years and between the first and 2nd gen explorers. You can actually swap the 1st gen upper aluminum intake manifold with a 2nd gen plastic intake manifold. There were a total of three intake manifolds that were used. An aluminum intake manifold and two plastic intake manifolds an early and a late model. Combine this with the AC delete (AC Delete) I did in an earlier thread makes this a much easier to work on engine.
Things to Know
1. Late model TPS and IAC will bolt to the early model throttle body/intake and function normally.
2. There is a bracket that holds the ignition coils to the aluminum intake. One side of the bracket bolts to the intake the other to the exhaust. Late model model exhaust does not have the bolt hole so you will have to cut part of the bracket off. Your coils will bolt directly to the late model bracket.
3. Late model plastic intakes use o-rings to seal to the fuel rail. Early intakes use a normal style intake manifold gasket.
4. 22mm-1.5 plug for the exhaust. Dorman 090-151
