JDM d15b IM VS. d16y8 IM
Does anyone know if the d16y8 intake manifold with its large plenum better or not compared to a JDM d15b intake manifold with its larger and shorter runners but smaller (d16z6 size) plenum? I got both but I can't decide which one to send to the machine shop to be worthy of a port and polish.
