CAI - To Whistle or Not to Whistle

Got the K&N installed and wonder if someone could help me here.

You know how they say it's bad to have extra parts at the end? Well I had an extra gasket that was supposed to go on the mass airflow adapter that I accidentally left out.

For the first week, there was no whistle. While checking the hose clamps yesterday, I noticed a good amount of air seeming to come from the hose between the tube and MAF sensor. I moved the clamp to the end of the silicone connector tubes for a better seal due to some advice I read someplace else.

I think I got a better seal now, but now I notice a distinct whistle sound at about 1/4 throttle. Is this normal or should I take the whole assembly apart and put in the gasket I left out during the install?

Little help?

Dunno can't see it.

I'm sure this is completely unrelated but when i installed the airlid on my camaro, there was a definite whistle, even at idle. It was just a side effect of not having the fins all over the top of the stock lid.

I'm sure the stock airbox in GTO's have a similar configuration, could be a side effect of that. Also K&N intakes regardless of model seem to make a lot more noise than they need to.

Good one.

My suspicion is that by the hoses not having a proper seal via the hose clamps for the first week, the air suction at the point where I omitted the gasket may not have been even enough to indicate that the gasket was absolutely required.

My fear is that since I've now corrected the hose/tube connections, the weak leak has shifted to the sans-gasket point where the sound may be created by this smaller concentrated leak.

I don't darnit feel like tearing the whole thing apart and inserting the gasket if someone can tell me a slight whistle normal.

If you didn't install one of the parts you have to redo it. The whistle is probably coming from a small leak where the piece in question should be. Why mess around? You spent a lot of money on the car and on the intake, might as well make sure its functioning at 100%.

I think the whistle is normal. I hear it with my LPE CAI. since the filter is in the open instaed of being in the box, you can just hear the air getting sicked in. My buddy used to have a '78 TA with the 6.6 and shaker hood, and with the shaker off and the filter exposed you could hear that SOB whistle from idle to WOT.

04 or 05 GTO?

A slight whistle noise is normal on an 05 GTO. Most 05 GTO's make a whistle sound with the stock intake. I don't know about the 04s.

I don't have a slight whistle, I have a turbo-like whistle with my CAI!!
Personally, I think it sounds COOL.
