This filter is white plastic. Clear plastic would be better. I cant see debris so Ill have to just remove and clean on a regular basis.

Filter was kind of small and not what I expected. I was unable to determine the inlet side so I called K&N. I was told by K&N that they do NOT make parts for aircraft so I put it on my shelf and will use it for my lawn mower.

I started my Avid Flyer to do some ground checks in 30 deg F temps on Xmas day. One of the barbs on both filters going int the Rotax 582 carbs. Wonder if it was a combo of the cold weather and vibrations. At least it happens on the ground :)
