REFLECTOR: XLFG Intake Air

[David Rene Dugas]

I think a filter is good. Like Scott I don't like even the thought of sand/dust in and machinery much less something that can kill me. When I clean my K&n filter I never see much detritus but I know it's there. My 2 cents. My engine is too expensive to dust. 😎

As I am nearing painting, and did not build this into the bird, the PO did, I'm considering eliminating the filtered lower NACA ram-air configuration for scat tubing to a cooling air NACA scoop topside for simplicity. As well the NACA down low where it is does catch considerable FOD from the nosewheel, yet is filtered.

If I were to make this change I fear I might lose a slight loss of manifold pressure, but for the simplicity would be better off overall. The sealing on the airbox to the lower cowl is problematic.
