    I just changed out my D16Y5 intake manifold with a D16Y8 Manifold and now I get an egr valve MiL light. How can I bypass this? Do I need to do an ECU swap? If so what else do i need to do?

    it allows better air flow to the cylinder head. which equals a little more power


    as far as the CEL goes, the y8 to my knowledge does not have an egr system, so ur screwed. i will research this swap a little more and if i find anything else out i will let u know

    Yes it will. There is a DIY around here somewhere. Do some searching.

    Why would anyone want to swap out just the intake manifolds? There are more things that are different between a y8 and a y5 motor then the egr valve. VTEC in the y5 head engages around 2800 rpm's and the y8 head around 4500 rpm's. The y5 has a 5-wire primary o2 sensor and the y8 has a 4-wire. The y5 doesn'y have a knock sensor and the y8 does.

    HX about to put on Skunk2 Pro Series Intake Manifold

    I have a 98 HX with the d16y5 (knew a guy with 280k on same motor, mine has 111k).
    I have 4-2-1 header, high flow cat (I extended the O2 wires and no CEL), custom exhaust and straight through muffler, AEM intake, and I am about to put on the skunk2 pro series intake manifold.
    I am going to have to disconnect the EGR but I am hoping that leaving it hooked up to wires and vacuum, tying it off to something, and not getting a code. I hope.
    I would really appreciate anyone telling me how they eliminated the EGR and avoided a CEL.
