    I am getting a high pitched faint whistling noise when accelerating. Sounds like it may be coming through air vents. Seems to be worse at highway speeds. Anyone experienced this?

    Sort of seems familiar. A couple of times I've heard something I might describe that way, but not all the time.

    A little of this and a little of that.
    I have a whistle but it sounds more like a turbo. It comes from my CAI. Sorry, I can't tell if I have what you have....

    Believe I heard from on here, this is from the screen mesh throttle body gasket

    Yes I had the same issue. If you will search around this forum you can find more information about it. If I recall it is the throttle body gasket. I took mine out and cut the mesh out of it, but still had the whistle sound. So I bought a throttle body gasket for the 4.7 I believe and it fixed the problem!

    So it wasn't actually a problem, just an annoyance?

    If it's just one of those things I can ignore it. I have a tendency to hear those things though and worry about what might be wrong.

    What I was hearing was a very high pitched whistle coming from the front passenger side.
    It wasn’t a problem it just drove me crazy lol

    Mine isn't super loud when it is there. If I have tunes playing I don't think I'd even hear it.

    Thanks for the info! Found the throttle body gasket thread. I'll definitely be doing this.

    FYI, they (dealership) even sell the gasket without the screen mesh

    Supercharger whine? :D could it be something stuck in one of the exterior vents, debris, leaves or a bunch of pine needles? If not the gasket...

    Could it be the ECM hissing/humming? There are a couples thread about it on here.

    Same problem here. I recently purchase a 2017 that had a K&N cold air intake and changed out the mesh gasket and it helped, but it still had an annoying high pitch whistle. I put the original air box bak on (came with the truck) and it still makes the noise. I’m thinking it could be the secondary air fan, but not sure of its location. I have about 1,500 miles of warranty left and would love to get this resolved.
