Often people don't understand what it means to be driving through talcum powder type dust that just lingers in the air around you. The Uni system I got from Todd is great, but where the Teryx draws its air from (OEM) is really lacking in thought and the reason for my snorkle. I don't mind doing the maint. (cleaning the filter), but the location of that filter and having to do it so often takes some of the fun out of it.
So far I haven't found any indication of it running rich, but will be watching it close.
How is your engine swap going?
