I pulled the DNA filters out of my XTR as fine dust was
getting passed them....
now use oiled foam...
Anything hi flow has to have big holes somewhere......
DNA / K & N style filters are great for road going bikes
but not on a bike that sees any dusty roads...
This is worth a read.... take note where the K & N/DNA style filters
came in all tests....
