does anyone know where I can get a replacement filter for my JLP ram air kit? my filter looks like its had it... its kinda sinking in the middle ...

also, anyone know how to keep these cleaner?? my is full of sand and dirt like every 2 weeks.... should I keep that black protective thing around the filter?

 

for daily driving you should definitely get that little bag, take it off when you go to the track.
You can get a K & N filter cleaner kit and it will work on the JLP filter. The filter is meant to be reusable. I have cleaned mine several times already.

I think almost any 12 inch filter will work.
