Better hope it ain't like mine. I bought one of hottuning years ago, tried fitting it yesterday and it fouled the engine/charger bracket. It's wierd, because they listed it for a mk2 polo 86c, but it has the same flange as the g40 one with the holes for the bracing bracket, yet no way it was gonna fit without cutting off bits of the charger bracket.
I did have to remove the charger bracket to fit the manifold though.. and then discovered it was a fail
