wrong mounted? this component on my Forester 99 points the other side and
downwards.

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! :)

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

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.
 
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 ,

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
