I have k & n came with quad though does the plastic piece that slides into air box come from k & n. I thought it was stock. I need something to seal filter mount to inside of air box.

I am trying to find just the foam that attaches to white air cleaner cage. That seals the cage to the air cleaner housing. My dealer says have to order the hole cage but I can't believe I am the only one to have the foam break down. Hope some body knows where I can get it I would really appreciate it.
