OTR oiled foam filter
 

Anybody have direct experience with the OTR air filter set up?

It appears to be a direct replacement (ie to fit in the same manner) as the OEM paper filter. Is this so?

Why is it necessary to replace the airbox cover to fit it?

Alternatively, open to suggestions of other brands of oiled foam element, if anyone knows of any?

I use these in my XTR...
If yer going anywhere near dust.. stay away from K&N / DNA style..
