I have a generic cone air filter. To mount it I removed all the stock intake, up until the airbox. Then I removed the top of the air box , removed the stock air filter, and attached the cone filter to the intake. The cone is resting on the bottom tray of the airbox. I tried removing the bottom of the airbox, but the the stock plastic intake did not support the weight of the cone filter. So now the cone is resting in the airbox. I saw some pics of people with the stock intake and a cone filter. How'd ya do it? Did u have to mount it in place somehow to support the weight?
