Do you have an aftermarket Blow Off Valve? Sorry, w/o anything else to go on, I come to the obvious.

TonyTurboII

did you put the restrictor pill in the hose to the airpump when you put on the intakes? maybe its the airpump

Can you elaborate on this? Are you supposed to do this? I dont think I did anything like this wehen installing my intake. Thanks.

Umm, shouldnt this be in the 2nd Gen section if its about a TII? It doesnt sound like anything but a bov to me.

hmmm sorry about that. can i get this moved to second gen please??

IMO it could be any intake pipe as well, since if the leack or the cut is not so big it might produce and sound like BOV...

af908

well when i got my apexi intakes it came with a very big restrictor pill that you are supposed to put in one of the hoses that goes from the airpump to the intakes. without this pill in it will sound like your car is "mooing". try unplugging the electrical connector to your airpump (dont keep it unplugged or your cat will clog up) and if the sound goes away then the a/p is the problem.

i think my car makes that moooing sound... Is it bad? It doesnt bother me too much. I like the look on th epassengers face when they think it is a cop or something.

My 7 has just started making this noise. It only happens when i hit 5psi. I could make an audio file of it, if anyone thinks that can help. I'll check back here but email me or IM me on aol shawntx76. I'd like to not be so worried about my turbo going out

1SxyRXy

yeah... could u, i want to see if its the same noise

af908

its about maybe 3/4 inch wide and its got a small hole in the middle to restrict air flow. but i have a third gen maybe second gens are different and dont need the pill

Shawntx76
