If anyone is interested I have a K&N air filter for sale model 33-2400 new in box still in the plastic. Can send pictures if needed. I know it would fit my wife's car but she has one already. I'm not sure what all models of XC90 it fits but I know it fits a 2007 Volvo XC90 due to it being the same one as the one in my XC90. However I don't need two of them, I got it by mistake. List for $50 USD will conceder all reasonable offers before listing on eBay.
