Good To Know

Q: How often should the air box filter and foam seal be replaced? A: Replace them at the interval listed in your sled's service schedule, and sooner if you ride in heavy powder or notice the foam seal losing its shape. A worn seal lets snow past the intake, so inspecting it each season is worthwhile.

Q: Does this require any modification to install? A: No, this assembly is made to fit the stock air box location on the listed Switchback 850 XCR models. Confirm your model year and serial number range before ordering to be sure of compatibility.

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