I dont know if the intake on the kit in that ad is bad.
The plenum certainly has a factor 1.5 and that is one of the most important things when going FI.
The one in the latter pic (not for an s54 i presume, no itb's!) I doubt the plenum has factor 1.5
Also the wedge shape is not positive, because of the function of the plenum. It is radically different than an NA intake.
