I was wondering if an intake manifold and a throttle body from a D16Y8 would fit onto a D16Y7?

 

Look for directions on installation, but yes, it will work. On a D16y7, to puy on a D16y8 intake manifold, the best way to do this is use your y7 Throttle Body and get a y8 Intake Manifold from a automatic Civic 96-98 EX. with one from a automatic, theres no IACV in the manifold, its in yout y7 TB which means you need not modify the manifold of TB. get one from a 96-98 automatic so theres no IACV on it and the 96-98 year will boly upto your y7 engine.
