The SR20DE/SR20DET IACV does not have an extra port for air from the intake piping:
The passageways are separated within the manifold/IACV. The only one from Xcessive which replicates this is 'Style 2', but as you see the body of the IACV is different as the Xcessive plate has 3 bolt holes and the DE/DET IACV has 4.
