At this point, I don't have a setup to test how well an element traps dirt.  I did take swipes on the interior of my airbox (downstream of the element).  The K&N wasn't letting any dirt get past.  With the Uni Pod, I would have to either remove the airbox and run it for a thousand miles or so, then take swipes on the interior of the carburetor, or set up some sort of dust generator.  I'm not planning to do that since I intend to keep the airbox, primarily for noise reduction, but I also feel it's a good setup that provides a plenum for air storage and also a longer intake tract from the inlet valves to the end of the hose connection at the airbox.  So, we must resort to asking the current users of the Uni Pod to comment on how well it keeps the crud out.  Lancer & Dave, how well does your Uni trap dirt?

At this point, I guess what I should do is see if I can get a little more out of the modified airbox.  I have some ideas but am concerned about noise.  Mine is currently pretty quiet so I guess I could live with a bit more racket.  I just can't sit by and let the Uni Pod garner all the glory.

Dave, I have to agree with your assumption based on dirt bike application, but have you ever inspected your carburetor inlet when you removed the pod filter, or taken swipes to check on how well it functions?  That would provide some concrete evidence that it does its job.  I'm sure it works well but some sort of definitive evidence would be good to corroborate the assumption.
