K & N whistle?

[rquintero]

Just installed a K&N filter in my Y2K. I'm 99.9% sure that the seal is seated properly and the installation is proper, but there is a "whistle" (not bad or loud, similar to what a spooling turbo would sound) in certain ranges during moderate acceleration.

So the question is: is this a normal characteristic of the filter element or is there a problem with my filter / install?

Just making sure I'm not hurting anything...

Mine also whistles. I like the sound a lot! Some people don't care for it I've read here before. It's my $59.95 turbo!!!

Impressions:
HP gain - 0
Fun factor - 100

Thanks James.

I like it too, definitely adds to the fun for very little $$.

I was just concerned about something being wrong and risking internal damage. I'll go whistle along now...

I think the whistle you hear is the sound of air flowing around the butterfly valve in the throttle body. I kind of like the sound.

But then again, I like sound. I prefer the sound of the car with the engine cover off, insulation removed, RM exhaust, CT straight pipes, intake, etc etc. Perhaps it helps that it is not a daliy driver.

Seen your car pics Chris, *really* nice!

I guess the OEM filter, being about 3x as thick, muffles that whistle then?

Chris is correct in saying that the whistle is the air moving across the throttle plate, or butterfly. I also think it's a very nice sound. It helps to keep you at mild throttle just to hear it!

Most likely the enclosed nature and thicker media probably muffles the sound.

You think that's cool, you should hear the GrouppeM unit!
