SnowCharger® Filter Wraps

The prefilter answer to all the snow that wants to pack down into the pleats of your snowmobile air filter. SnowChargers are silicone treated polyester wraps that repel snow and water. Melting snow just beads off instead of soaking the filters.

  • SnowChargers will stop small dirt particles, yet add little restriction to the airflow of your filter.
  • Deflects grass, twigs, rocks and dust you encounter when grass track racing or crossing snowless trails.
  • The SnowCharger is designed to be run dry and can be easily cleaned with K&N Filter Cleaner.
