Double the surface area, Twice as effective.   

FWF's filter has been designed to address the intricacies of the 790/890's air box and it's unique filter fitting system

The filter pad is dual layer – pyramid profiled foam bonded to a second flat layer which also seals the pad into the cartridge. 

The replacement foam pad is easy to clean or oil.
Whist the foam layer bonded to the cartridge will not always require cleaning, it is a little more difficult to service and will require aerosol filter oil for best results but is a far safer alternative than a removable piece of foam.

The Filter Foam:

• Dual layer foam
• Pyramid profile design
• Removable from Filter Cartridge
• Replacement Primary foam filter available (P# FWF502)

Kit Includes:

• 1x Filter Foam Pad
