Wraps around your K&N filter to keep water and small particles out of the filter itself. K&N DryChargers are manufactured from a durable polyester material and are pre-treated with a proprietary hydrophobic process designed to prevent splashes of water or mud from saturating your K&N air filter. The DryCharger will also stop small dirt particles; yet add little restriction to the airflow of the filter. The DryCharger can be installed under the Foam Wrap.

This is the more economical alternative to eliminating the 990 Adventure airbox. Better breathing equals more power. The ITG filter kit makes air filter service a snap. It also simplifies other engine and intake maintenance chores. Our kit features a steel base plate which will not deform like plastic and does not conduct heat as much as aluminum. The white powder coating also helps reflect engine heat. To take advantage of the increased airflow, we recommend upgrading your fuel injection map with TuneEcu or a Power Commander.
