[Land-speed] Screen

[bobbyhotrods at comcast.net]

Has anyone ever seen a puny filter or screen on an intake for a turbo? My deal's really pretty tight, with the intake facing the block only about an 1 1/2" away. I should have something there to keep at least the larger fasteners from going in. 4" diameter.
Alternately I'll make something, maybe using foam and a screen. Any foam experts out there? Thanks, BJ in Beantown, where the Sox finished in front of the Yankees.....
