[2fast4you209]

Does any one know the diffrence between the d16y8 99 intake manifold and the 96 one. Well my question is on the 96 the (iac) is in ita normal location on the back of the manifold, but i got what i was i was told was a 99 ex manifold and it is diffrent it still has the y8 look it just has a extra vac. line in the center on the flange and the (iac) is on the T.B.. Is this a 99usdm 99 ex or 96+ jdm or what? Thanks Rob

i have a 99 intake, the only difference is the air injection port(middle of the runners against the block). the auto and manual ARE different though. manual has IACV on the back of the block and auto its in the TB. you got a automatic one im gonna guess. you can drill the holes for the iacv if you want, there are a couple of write-ups on it
