FWF's filter has been designed to address the intricacies of the 790's airbox and it's unique filter fitting system Special attention has been given to the filter seal, arguably the most important component. The injection-moulded seal been specifically fabricated for this airbox’s filter securing system having dual sealing lips incorporating a ‘U’ channel for the application of a sealant (grease). The removable filter pad is dual-layer – pyramid profiled foam bonded to a second flat layer which also seals the pad into the cartridge. A further foam layer is permanently bonded to the filter cartridge to trap any dust particles which may bypass the filter pad in extremely dusty conditions. This provides three layers of protection without sacrificing airflow. The replacement foam pad is easy to clean or oil and can be purchased separately as a spare. 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.
