Need 318 four barrel intake

There is no performance difference in the non EGR and the GER intake manifold. The problem with the EGR intake is sealing it off. If you do not have the valve or gasket, it can be a pain to locate the valve and/or gasket.

The valve only opens during cruise, closes at a hard acceleration or W.O.T.
The exhaust gas is inert and doesn't hurt cruising power.
