So i've noticed that some rangers have upper intake manifolds that have 2 runners and some of them (later models) have 4 intake runners. My 1994 mazda 2300 has the 2 upper intake runners that leads to the intake plenum and opens up to 4 intake runners for each cylinder. I'm wondering if swapping the 2 runner upper intake manifold for a 4 runner upper intake manifold will have any performance gains. I notice that there are a few minor differences like where the vacuum ports are, but seems like if you can find the right one, or maybe even swap the lower manifold with it, it'll bolt up easily and just may have to reroute some vacuum lines.
