does anybodys K&N whistle?
so i got my K&N CAI last week and i started hearing this whistling. well im like wtf mate what could that be so i pop the hood and have my friend slowly drive up the driveway.
well it seemed to be coming from the filter, so i was like now i have to buy a new filter.
so i got the new filter today and it does the same damn thing
so does anybody else's whistle? its only at lower speeds usually in between 1-2000RPM and when i press on the gas
if no one else's does this then im about to scrap the k&n for an AF1 or something

For me (and AFE) it kinnda whistles, but it's more a noise of it sucking in air. It only does it when I push on the throttle in the low RPM's, and only for a little bit. If I really look for it, I can make it slightly whistle constantly, but it's only at a very small RPM range.
Really, you get used to it, and I personally like it, especially the growling part.

If you have a whistle from your K & N I would bet you removed the small black plastic muffler that was installed by Ford. I don't have a picture but it is about 2 by 4 inches, black plastic with a hose at each end.
Mine did the whistle and to get rid of it I bought a small piece of hose with a 90 degree bend in it and put the muffler device back in line.

My 3" AF1 never whistled, but there was a distinct "whoosh" sound when steppin' on it from low revs.
For some reason that sound has all but disappeared since I started running the tunes from Troyer.
I think the induction sounds are normal with any "cai", but there shouldn't be anything high-pitched. Like a whistle noise.

see thats what im thinking, mine does roar when i step on it and i know they are louder but i wouldnt think anything would be making a whistling noise.
it sound just make a whoosh sound from sucking air in.
this is a loud pitched whistle too, i can hear it inside the truck when i dont have any music playing and the windows up.

Yeah, there has to be a leak or loose connection there somewhere. K&N is a high quality intake... you shouldn't be getting a whistle.
I'd double check everything (sounds like you have already though), and if you don't find the problem try contacting K&N. It sure doesn't sound normal.
