It could be to do with the n75 nipples on the turbo, for the air passing over it making a sound like blowing across the top of a milk bottle. But saying that I have never noticed it on a k04?

I'll keep mine on till the 24th :happy2: and you can hear it on mine
could it be air passing by the maf? the oem intake has a mesh just before the maf i noticed?

^^^^
Did someone mention nipples? :evilgrin:
I still don't get an answer on Forge's published phone number! :fighting: I was going to ask them about it.

I have this also sometimes on my k03 GTI, but for some reason its very rare now. In fact I cannot remember hearing it for days. I have heat wrapped my intake so maybe that helped a bit.
And I had the same ITG intake on my Leon Cupra (k04) and as Nick here said, I never heard this sound in that car.

i spoke to ITG about this and they said they experienced it on a small number of cars but couldn't explain why

Interesting development.
First a tiny background on my specific intake. I bought it from a guy who had it fitted for a few weeks but removed as it whistled. ITG sent him the enclosed canister to see if that fixed it. It didnt. So he sold the whole kit... to me.
I sent Andy at ITG the sound file.. its the same sound as the previous owner was getting. Andy sent me a video clip the other guy sent him and its exactly the same noise (although possibly a bit worse on his car.
I'll try to post the video.
