Good To Know

Q: When should the air box filter and foam seal be replaced? A: Follow the replacement interval in your sled's service manual, and replace earlier if you ride in deep powder or see the foam seal flattening out. A compressed seal allows snow to bypass the intake, so check it every season.

Q: Is any modification needed to install this? A: No, this assembly is designed for the stock air box position on the listed Switchback 850 Pro-S models. Verify your model year and serial number before ordering to confirm the fit.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
