I put a d16z6 intake manifold on my d15b7 and im not exactly sure how the hoses are supposed to be hooked up and if i should plug one of the ports or not? Can anybody help me out? Thanks

 

The D15B8 and D16Z6 have the same routing, I just haven't had a chance to change the picture to say so. In any case, just cap off or plug the extra line or switch the water pipe so you have the matching one to the manifold.
