I'll agree whole hardly on that one! I can't tell how many hours it took me to get those bastards off! A socket was about the only way I could get them off!

Just did mine last night and thought I would share my experience as well in hopes that in might help others.

I had been living with a "squealing" noise when under throttle at low RPMs...for example when nearly "lugging" the engine in third gear at 1000-1500rpms.

Bought the upper and lower intake tubes and started the process.

I removed the airbox with MAF but not the intake portion over the grill holes. Wow it was tight in there. Screws on the hose clamps facing downward of course.

I did end up removing the cabin filter housing...not because it gave me any more room but it allowed access to the clip that let me remove the heat/splash shield near the brake booster. Getting that shield out is a little finicky but it gave me more room to work.

6mm socket with a swivel attachment is invaluable here...much better than a slotted screwdriver for those hose clamp screws.

When I pulled the vacuum line from the upper intake tube, the lower hose disentegrated in my hand...that could have been the cause of the noise but I'm not sure. I didn't see any obvious leaks or tears in the upper or lower intake tubes but after replacing both and replacing the small hose that disentegrated with a small piece of rubber hose from a brake bleeding kit the "squeal" seems to be gone thankfully.

Now I need to redo the front suspension and rear shocks this weekend.

Thanks for those who shared their experiences. This should be a 15 minute job if everything was easily accessible but due to the tightness of the space it took me over an hour.

Just did this job myself too, and like others the hose clamp orientations on the boots could not have been more awkward. But I was able to lean in from above with a nut driver and contourt my hand / mouth / eyeballs enough to get the tool under there and get the clamps loose. Once loose, boot removal and reinstall was a piece of cake. Inspected my DISA and replaced it's o-ring while I was in there.

I was not blowing any lean codes, but original boots were 12 years old and were starting to look a bit rough. No cracks were found, but there were a few spots where it was apparant that it was just a matter of time. Oh, and a GSA DISA rebuild kit is on it's way.

Next up on the punch list; front wheel bearings and a new fuel filter. Wish me luck!

I too, had a SES accompanied with whistling. I'm thinking of DIY'ing this - but my mechanic said that he normally replaces both the upper and lower boot. Is this recommended, or just unnecessary?

I had this problem recently and could not pinpoint where and how was it happend. I know the sound came from general area where the intake tubes are. So I took it to a dealer and they could not duplicate the issue. By the way it only generated a whistle sound when engine gets hot, morning driving is OK but after work on my way home it does it. I am glad that I found this thread. First, Thanks for a DIY write up. It's just perfect. I did it within 1hr45. Agree that those hose claims are tough to reach and not much room to get the tool in, just be cool, you will get them out eventually. Anyway, inspected the elbow, cracked, replace a new tube elbow, thought that the whistling sound went away after 30 miles but then they came back. Notice that at the stop light while that sound was on I released brake paddle and applied brake again and the sound went away so i repeated the process while driving with sound on and magically the sound stopped. Is it possible the whistle sound somehow relate to the brake ???? BTW, it's 2003, 330i, approximately 61,000 on it

If one wants to pinpoint a vacuum leak without wasting time scratching one's head and unnecessarily replacing parts one after the other, all one has to do is a what's called a smoke test. Diagnose it, don't just throw parts at the problem.

DIY: Intake boot replacement. No more whistle while accelerating

Is there a part # for this connection peice? Or do the boots simply slide on top one another?

Thanks!
I did it like 4 years ago and I do recall this issue. There was something like a connection piece inside the old boot I think

Thanks for the write-up OP, I was feeling pretty sorry that this took me over an hour to do but then I saw that some people were taking 2+ and some poor soul went for 6 hours? How many beer breaks do you reckon were taken? Anyways, feeling much better now.

Thanks for this DIY, I found it really helpful replacing my lower intake boot and cleaning my ICV today.

Using a flexible extension like this helped a lot getting that lower intake boot out.

Glad people found this helpful.

Also if I may add to ease removing the clips a flexible screw driver (looks like a tightly coiled spring) and a 6mm socket works wonders on removing these hose clamps throughout the engine.

Here's what I use, just a pic to show you guys what the tool looks like. It makes many repairs easy, (no need to buy snap-on unless you do it professionally)

I just did this diy (well in the middle of it). I am on the reinstall part now and the lower intake boot is already installed. So now I am at the point of attaching the upper intake boot to the lower one, however for the life of me can't figure out how to attach the two together as it is a rubber to rubber connection, like the reinstall of step 11. If someone could chime in that would be great.

I had the same issue. There is actually a plastic piece that goes in between the boots and is the connection. Most likely is was on the old boots and you threw it away ( ask me how I know). Anyways, they are relatively cheap to pick up

Yeah found it. I was just standing there thinking wtf?! There is no way possible this is right but everything is right in front of me lol. It was just attached to the old one like you said. Ironic though how none of the diy videos comment on the piece
