My car has the evo airbox on it but I am missing the rubber rail and foam donut without k&n filter. There is also a couple holes from where the power steering belt rubbed on the bottom. I could repair it with some epoxy if I can buy the other pieces seperately. Can i buy the other pieces seperately and how much? Is it worth it? Where is the cheapest place to buy the complete evo airbox with k&n filter?
