All IO-550 users;

I'm getting close to hanging the engine (IO-550) on my ES and am wondering
how others are handling the air intake (airbox) problem.  I would very much
like to have direct ram air available as well as warmer filtered air for
ground operation and potential icing conditions.  I'm thinking of a "Y"
arrangement where one side goes directly to the cowl opening and the other
is filtered and draws air from below the engine.  A pair of butterfly valves
would accomplish the switch over.  Is anyone aware if such an arrangement is
in use and where I might get the parts?
I would be interested in any other solutions which effectively accomplish
the same objective.

All suggestions are appreciated.
