[Vwdiesel] torque drop in warm weather, was....

[Scott Kair]

     A timely thread.  When I was changing my air filter over the weekend I
looked over the air box on my 92 Jetta ECO.  Very interesting arrangement.
    One inlet seems to be from the grill.  There didn't seem to be much
deterioration of the foam seal around it, as mentioned previously.  But
there was also some sort of intake horn pointing towards the rear of the
engine, towards the exhaust manifold.  It ends in the filter box at a
spring-loaded door.
    Bentley didn't seem to mention it.  What would this one be for- a heated
air intake?  Perhaps the intention is to allow supplemental intake under
load?  I'd attributed power loss above 85F to running the a/c, but this has
me wondering.
    TIA
