3 Stage Intake Manifold.

Hey, quick question. I bought this 3 stage intake manifold a while ago, I should have verified this before I bought it. But does anyone know if this particular one will work? Apparently its from a 528i f10? The silver metal thing it supposed to cool the air that is going through the manifold. I've looked around and can't find that much info about it. Any additional information would be great too!

looks right. Silver thing you can remove if you don't want it/can't fit.

What is the part number listed on the manifold? Start from there. Get the number, google it and see what comes up.

Wow, I have never seen that metal thing on these intake manifolds before. And not so sure how it is suppose to cool the intake air, but anyway, interesting.

It functions as a heat sink to remove heat from the manifold.

Yeah, I read that it's a heat sink. However there is no way that I can remove it, because it leave two huge holes in the intake lol. Everything else looks to be fine. I'll just be able to use this as an excuse to call it my rare "racecar" part.

Yep, in theory I understand what it is suppose to do, but I just can't see how it could be very effective really since the intake is made out of a not so heat conductive material to begin with, so the metal is only really going to take a small amount of heat away, and it is not even making contact with all the intake port runners. Doesn't seem to be very practical...

yeah, and on top of that, it's under the hood. not like it's getting a steady stream of cool fresh air flowing over it.

That's where the DME is in the F10. Air cooled from the intake manifold. M

That's interesting, so the DME needs to be cooled from the intake cooling this heat sink - been trying to find an engine bay with this setup, but gather it must be one of the more recent N52 engine versions that have a completely different engine cover that covers the engine and intake (so you won't see this heat sink)...

N20 and N55 engines have the DME on or under the intake manifold. N52 made it to the first year of the F10 and the F25.

BMW is know for using the old engines on the first year of a new generation. The E60 came out with the M54 and later transition to the N52. The new 5 and X3 first came out with the N52 and the the N20.

Yep, they do. Pretty odd place for the DME, but that's BMW...
