Having destroyed my factory intake manifold in, let's say, a tuning mishap, I believed that all these intakes were the same and bought a take-off one from Ebay. I have a very late '14 automatic with the weird one '15 cylinder head and one '14 casting.
The two manifolds ARE different, as I found when attempting install.
The photos explain. The reinforcing ribbing is much larger on the 11-? IM and cut back on the 14 IM, probably to clear the 15 head's straighter flanges. It doesn't look unmodifiable to fit but, now I need to surgery the mani, when I hoped it would drop on.
Another thing confusing me is, as I took the manifold off without labelling, duh, there is a large hose connection at the back of the intake (similar to pcv hose fittings at the front) but, I've got nothing to connect to it, it seems. There is a strange loop of vac hose back there that goes down to the trans but, it won't fit over that fitting and doesn't seem to have anywhere to go, either. The 14 mani has the same fitting so, it must have done something??? Anybody let me know what both things are?
