I have this intake manifold from an MP3. I’m confused as to what the true differences between this and my regular manifold are. I understand that the MP3 version is supposed to have VICS but not VTCS, and while this manifold only has one solenoid on the top, I still see two vacuum actuated butterflies.
Is this a true MP3 intake manifold, and if so, why are there still two sets of butterflies?
