This extra thick filtering medium provides the increased protection demanded by high dust conditions while continuing to provide the performance necessary to stay in the front of the pack. The XD Cotton medium was developed for the extreme conditions encountered by race teams in the Baja 1000. This real world testing is combined with testing performed at K\u0026amp;N's own Dust Retention Laboratory in conformity with the ISO 5011 test protocol. XD Cotton Air filters can be cleaned in the same way as K\u0026amp;N's original cotton air filters.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDesigned To Boost Horsepower And Acceleration\u003c\/li\u003e\n\u003cli\u003eWashable And Reusable\u003c\/li\u003e\n\u003cli\u003eHigh Air Flow With Exceptional Filtration\u003c\/li\u003e\n\u003cli\u003eLasts Up To 50000 Miles Before Cleaning\u003c\/li\u003e\n\u003cli\u003eWorks With Original Equip.
