Default Intake Elbow question

So I was looking at the one on my car the other day and I noticed that my elbow thats in the fender and wraps from the itake box to the ram air (or whatever its called) under the hood has a hole in the bottom of it. So should the hole in the bottom of my "intake elbow" be covered.....like is it disrupting the cars "normal" air flow intake that comes from the plastic piece under the hood?


fyi this is a actual elbow with a hole in the bottom about 1.5in wide. It is NOT the oem piece with the lower "bucket" just cut off.

Reason I ask is because my car has like a "raspy" intake sound when I get into it. And I was thinking that maybe the intake sucking in air the normal way and through this hole is causing a disturbance in the incoming air and causing the sound.


And all pipes/tubes and hoses seem to be fine and connected.

Not sure what a 2004 "bugeye" WRX is, but when I had an 04 WRX I cut the lower bucket off the elbow. The only change to the intake sounds I remember were the BPV was audible, very similar to an aftermarket intake. A little quieter, but no raspy intake noises.

Try taking the elbow out or just tape over the hole and see if the noise changes.

I have a 2004 wrx with a bugeye front end conversion.

Ya I may tape that hole and see what it does. That way the ari will be coming in the way its supposed to rather than 2 different ways.

raspy intake sound is not from a small hole in the elbow.


matter of fact, the only noise that would get louder is the turbo and bpv sound

That hole is for water to drain out if it ends up in the pre-filter intake tract. It's supposed to be there.

Is that hole not at the lowest point in the pre-filter intake path?

Take a picture of it. Your description made it seem too big for an OEM hole, a 1.5" hole is pretty big.

Are you hearing WG flutter? You probably need a video.
