OK well to me Jules shield sounds like something an orthodontist might use, plenum chamber sounds like a part of the body.
Not heard of an MG ZT either (only Midget).
So I live and learn.
PS men are sexywhen they get all technical about cars :-))
Well not really a replacement part, but an add on part someone ( Jules ) has invented as an add on to prevent leaves getting in and clogging the plenum chamber.
