Twin Air Pre-Oiled Dust Cover 154116DCX

Fit this over your Twin Air filter when riding in severe conditions such as heavy dust or sand.  This coarse foam pre-filter will act as an additional layer of protection and extend the service time between filter cleaning.

A Pre Oiled filter is submerged in Bio Liquid Power Oil and massaged to ensure all the pores are evenly coated.  Its then placed in a temperature-controlled room to allow the oil to cure.  You just have to install it and use it.
