Should my lager or cider kit include an airlock and grommet?

You do not need an airlock and grommet as this contains a spindle and carbon block which achieves the same result as an airlock and grommet.

This is already fitted into the lid. You do not need to do anything with it. If you have removed it and replaced it then please do not screw it too tight, it should be slightly loose in order to let the gas escape.
