60 Shipped for continental US. Filter and box are in good used condition.
I would much prefer to sell them together. Having an extra airbox means you can perforate the one that comes with the K&N, as some people have been happier with their performance doing so. Will be sent out same day payment is received or next am if after hours. my paypal is mwillia5@uvm.edu
