Thanks Ben,

I was going to do something like that before I stumbled on the AEM's,
but couldn't figure out how to build a simple reliable way to open the
alternate source.  That looks pretty good.  My intake is a 2.75" dia
tube straight into the throttle body, so I would have to put in a 'T'
and run a hose to a box with flat sides to use that method.  

If that works OK for the Subaru, the AEM should work OK too.  It uses a
bunch of plastic flappers around both sides.  It also uses foam to
provide the spring function and keep the flappers closed, and has a foam
layer on the outside also.  I like the idea of that as I still have some
level of filtering even with alternate air.
