Was told that an Outerwear sticks to the foam filters so should only use them with K&N filter. However, they said if want a pre-filter for foam to use the PC Racing filter skins. Anyone running these. And if so, they are not custom fit so which one did you get to fit the filter ???

 

I have all ways used Outerwears with my Proflows. I have the same setup on both Raptors.

 

i use outerwears on pro-flow

i find myself cleaning oil off the outerwear,,,,,usually when I over-oil the filter

works fine though
