Just to clarify, that is not an S1E1 intake manifold . The S1E1 used a casting without the water manifold and an insulating mounting plate between the head and manifold whereas The SQ has the water manifold integral to the casting. There are a few other minor differences. It looks the same from the top.

I'm also surprised to see KV listed. The SQ engine code is KW if that what the seller was trying to relay.

I expect that item to get above 1750 Euros easily, but two lousy pictures and a two errors in the listing... Very Poor, that will cost his maybe 500 Euros right there.
