Essentially they are the same, except the non supercharged has an EGR fitting and the supercharged one doesn't. Some brands use slightly bigger primaries on supercharged extractors too. You can use the N/A ones on the S/C car as long as the EGR fitting isn't actually drilled through. As a matter of interest, I do both.

Exhaust Gas Reticulation Valve - recycles unburnt fuels into the manifold to be reburnt. An emissions requirement and tool, some recommend to close if off with benefits of cooling the intake charge, or so it goes. Although the car will not pass emissions anymore.
