The rear baffle was used on both versions. It is a splash shield. The adapter (6A665) is a vapor/fume separator.

This is especially important when using the MOROSO PCV valve grommet. Usually this baffle has to have the adapter retaining nut drilled out to allow the valve to fully seat. This exposes the valve to splash.
