This prolongs the life and durability of the filter. The rubber used in BMC air filtering systems has a long life with optimum adhesion characteristics to all shapes of airboxes.BMC filters are made of multi-layered cotton gauze soaked with low viscosity oil covered enclosed in an epoxy coated alloy mesh to ensure protection from petrol fumes and oxidization due.All BMC air filters are pre-oiled, and they can be washed and regenerated by using the appropriate BMC regeneration kits.BMC equips teams in Formula 1, MotoGP, WorldSBK, 24H of Le MansMade in Italy.Specifications:Shape: CylindricalOutside width: 55mm Outside height: 98mm Height: 100mm Package Quantity: 1Package Contents: 1 Air FilterFilter Material: Oiled Cotton GauzeWashable?: YesWarranty: 2 Year LimitedWeight: 0.21KG EAN: 8055732596422 Type: CylindricalOEM Part #: 0K&N Part #: 0 Fitment Make Model Year NORTON COMMANDO 961 CAFE' RACER (OEM NO6200111, NO6200005) 11>17 NORTON COMMANDO 961 SF (OEM NO6200111, NO6200005) 11>17 NORTON COMMANDO 961 SPORT MK II (OEM NO6200111, NO6200005) 11>17 NORTON DOMINATOR 961 (OEM NO6200111, NO6200005) 11>17 NORTON DOMINATOR 961 SS (OEM NO6200111, NO6200005) 13>17
