w/e 1 u have plugs for s5 is barely any more hp prolly not noticeable on a n/a. its gonna be loud. if u want u can switch over ur sensors and such and get that tiny bit more. but might need to extend some wires since s4 and s5 the intakes come in on opposite sides.

If you're talking about NA manifolds, the S5 manifold is both longer and shorter than the S4 due to the VDI system. Short runners are better suited to high RPM operation, which is where your gains from a bridgeport would come. But I don't think you'll get the full potential of the port with even the S5. The engine will probably want to keep making power, but the intake will eventually restrict it.

Neither one is very good for an NA bridge, but both will work.
If you must use a stock NA manifold, use the S4 manifold.
If you can, gut the plenum chamber to remove the DEI effect.
Even better would be the TII manifold port matched to the NA block.
Better still is a set of nice ITBs with a Weber style wraparound manifold.
