Finally installed the intake. When I first started it, I could hear the DISA's going and thought something was wrong cause it was pretty noisy and constant. After turning the car off to put on the covers and starting back up, no noise. Sounds like normal now. Drives about like before, but I did notice on the freeway on ramp, that @3500-4k RPM, it doesn't pull as hard or the flat spot everyone has mentioned. Already ordered the OFT and hopefully it's here on monday although there is no OTS for a 325i yet. Hear Vishnu can smooth out the throttle though.

I wasn't sure which DISA cable to connect to which DISA as I was pretty sure the cables were moved around before so just saying the one closest to the front goes to X doesn't help. I did notice one was longer than the other and I ended up connecting that one to the DISA modula under the intake manifold and the shorter cable to the module above the throttle body. Hopefully this is correct.

Short cable to the underside disa I believe, the longer cable on the outiside.

There is a good tutorial on z4 and 1addicts with photos

EDIT: LONG is inner disa, short is outside

Mostly I went with the pics on this thread showing the DISA cable circled for which goes where and that would be great if I was 100% sure they were still mounted in the same locations. Still though, I think it's very hit or miss, especially when one cable is different than the other. One cable is longer than the other. One cable is positioned differently on the wire block/holder under the throttle body than the other. Why not use those discriptors to say which goes where?

I decided the longer one was suppose to go on the DISA under the intake because the shorter cable would just barely reach and it would also crossover the longer cable on the wire-block. And then I'd be connecting the longer cable to the DISA above the throttle bottle which would then have a lot of slack. Makes no sense that way.

I read the 1addicts DIY, but must have glossed over without catching this part

The longer DISA wire closest to the front of the car is for the DISA actuator under the intake runners. The shorter DISA wire is for the DISA actuator above the throttle body. You can remove the DISA wires and their cap/mount from the stock manifold by lightly prying the clip from the manifold and sliding them down. You also need to disconnect the wiring junction box at the base of the manifold from the manifold.

Long cable is to the underside and short cable to the DISA above throttle body.

Hey Guys,

Extremly noob question but based on pictures i think i have already a 3-stage intage. I based this on the following pictures.

This is what a stock engine bay looks like

MY engine bay looks identical to the last picture except for the after market air box but the intake manifold is identical with the BMW letters and all.

See!! how do i tell if i have one of not? i bought the car used so maybe the last owner did it? BTW i drive a 2011 LCI E90 328i

What you have there is a pic of a dirty engine bay with the BMW snap on cover missing from the intake manifold compared to a cleaner engine bay with the cover on, as well as an afe airbox. That's all I see there. That BMW lettering is just a cover, all the N5x motors have it. If you want, you can pull it off and your engine bay will look just like the first pic.

A "3-stage engine bay" looks exactly like a non-"3-stage engine bay", except for the 2 DISA valves that most people wouldn't notice one way or the other if they weren't looking for it specifically.

What you need to look for are DISA valves on your intake manifold. One is above the throttle body and easy to see, the other is under the intake manifold runners and easy to see as well. If you have both DISA valves , then you have a 3-stage intake.

Those two engine bay looks exactly the same lol. The BMW cover on the first pic has been remove (it just snaps right on top of the manifold. It will be hard to tell but you go new a flashlight to see if there is an actuator on both side of the intake manifold. One facing the engine and the other facing away from the engine.

Do you know if your car is SULEV or not?

[mike-y]

you need to look in the circled area for a surface mounted "box" with a cable going to it. if it's NOT a 3-stage, there should be 2 unused plugs clipped to the manifold in that location instead.

you have ruin my day hahaha i have two unused plugs there UGH!! oh well on the hunt for a 3-stage intake then!

PS: thank you to the rest of yall for the responses and teaching me there bmw letters is just a cover.....oops

Would the manifold from a 2003 530i or 2005 x5 work?

After doing a bit of research it seems they're identical to that of a 2006 330i. Or am I missing something?

They would work. The only thing to look out for is if the oil separator is attached or not. If it is, you have a do a bit of cutting and plugging up of holes but nothing difficult

I'd like to avoid cutting and plugging, if possible. Turns out finding a used, 100% compatible manifold is tougher than I thought.

Is there a list of equivalent years/models that use the same intake manifold as the '06 330i around somewhere? I can't seem to find one, and running the part number through realoem.com doesn't quite narrow it down completely.

I got one that is a 06 530i.... but ran into this issue... so need to do some plugging http://www.e90post.com/forums/showthread.php?p=15347646

I got mine from a N51 bmw and it was a direct fit. I would go with one of those

I agree, that would definitely be my first choice.

This is exactly what I needed! Thanks!

[DickBlisken]

Ok, so I tracked down a manifold and DISA valves from an N51 328i, and I'm pretty excited!

I'm going to be installing it in my 2009 E92 328i, which means that I do not need to purchase the vent hose (11617559530) as well, correct?

Here are some photos, for reference:

[mike-y]

correct, your existing hose will work. BUT, you still might want to get one just in case you crack yours trying to remove it, which happens to a lot of people.

Thought so. I'll be careful!

[DickBlisken]

So, as I had mentioned, the manifold I purchased is from an N51 328xi. That being said, which set of hardware would I purchase? I've been different sets in different DIY threads.

11617535849 x5 Screw 50x20
11617535850 x2 Screw 50x35
11617535851 x1 Screw 50x66

or

07119903918 4x manifold hex bolts w/ washer
07129905541 3x manifold hex nuts w/ plate

I know I'm asking a ton of noob questions, and I've been searching as well but haven't been able to come to solid conclusions. I want to be 100% sure!

If the manifold comes with the actuator motors attached you won't need any of that. But you will need a gasket set.
