Forgive me for being out of touch, but I need what is probably commonly-available information.  I will be installing an IO-550 (non-turbo) in my unpressurized Lancair IV.  What is the recommended induction air configuration to get filtered air into the intake?  I presume that there is a Legacy factory configuration for air filter and induction tube to the intake manifold.  Is there one for the Lancair IV?  Are they the same?  Or are folks mounting the conical B&N air filters in the upper cowl area (as I have seen at least once) with an elbow, and going with that?  Other ideas?  Photos are always welcome.

Many thanks for your help.
