Where do I get a foam prefilter??

[NacsMXer]

Ive been looking all over and I can't seem to find a foam prefilter wrap to oil and put over my K&N. The outerwear that I have on there is great for keeping out the big particles, but sucks the mail for keeping out the fine dust that I primarily ride in. Where can I get one of those buggers? Thanks a lot.

try calling K&N and asking them cause i never even heard of that and why would you do that cause it will sacrifice the extra air the K&N offers compared to the uni......Wait maybe if that is what you want try taking the foam filter outer wear off of an Uni filter and use that.

I didn't know what other people were using for their foam prewraps thats all. Ive heard of it here and there and Laz at GT Thunder recommends putting a foam prefilter over a K&N. I already have a K&N so I thought I would give it a shot.
