    Hi All,

    I'm trying to find out what this component of the air intake is called
    and what does it do? See picture site below. 1998 Forester 2.5L.

    Here is the URL of the picture:

    Thanks ,

  2. that's a resonator or something I think - noise cancelation I guess.

  3. Oh, my. I think Sigmund Freud could answer that question best.

    Thanks for the response Wilco. That tube is pictured in the 1998
    Legacy manual in the same position as mine. Also the bottom side of
    the tube is formed so as to accomodate the spark plug wires to pass
    below it. It might be the case that it really doesn't matter what
    position it is in.

    I wonder if Subaru knows what it is for! :)

    I believe you're close to the answer. My guess would be that it has to do
    with tuning the intake so that when pressure waves bounce back and forth they
    arrive at the intake valve just as it opens. Or maybe not.

    It is a resonator chamber. AFAIK, it is to help damp out pulsations in the
    intake air flow and make the readings from the MAF sensor more accurate.

    Later,
    Joe
