Good To Know

Q: How often should the air box filter and foam seal be replaced? A: Inspect the filter and seal at the start of each season and clean or replace them whenever they show dirt buildup, tears, or loss of sealing. Snow dust and moisture exposure can degrade foam seals over time.

Q: Does this fit both halves of the air box? A: This item covers the air box filter element and foam seal as described for the listed Polaris SKS 850 model years. Confirm your specific air box configuration and model year before ordering.

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