Has anyone bought or made a custom air box for the K&N FIPK system. I was going to fabricate my own but I thought I would check on here first. I saw that volant has an air box but , 1. i dont think it will fit straight up on the K&N without modding it and 2. I cant find anyone to sell me just the box itself. anyone got any ideas, or an old box they wanna let go for cheap?
