4 BBL intake manifolds

I don’t have a V12, so i’m not in the loop of all the aftermarket parts.
Never seen or heard of these. Are they of any value ?

Certainly wouldn’t fit under the hood of an XJ-S. I’m sure some people appreciate 4 bbl’s, but to me they are endlessly frustrating – especially when there’s two of them. Perhaps an improvement on the Stranglebergs and perhaps even on the D Jetronic, but certainly a big step down from the Digital P and nowhere near a decent Megasquirt setup.
