FunnelWeb Foam Seal Motorcycle Air Filter (FWF431)

Part No. FWF431
Trap and hold more dust on the outside surface of the filter
Maintain optimal air flow by spreading dust build over an increased surface area.
Enable longer filter service intervals.
The Foam Profile:
Provides a 100% larger surface to trap more dust
Traps dust evenly over the increased outside surface area while allowing optimum airflow for longer periods of riding
Effectively reduces the frequency of filter changes and cleanings.
The Seal:
Any air filter is only as good as its seal. Most of the genuine, Australian made, FunnelWeb Filter seals are injection moulded urethane or a die cut, urethane / foam combination.
These seals will not shrink, stretch or tear and will maintain their shape, regardless of how they are treated ensuring any air entering your engine passes through the filter foam.
In some cases, air box design dictates the use of foam only seals which is where we use die cut polyurethane foam to do the job.
Developed and Tested in Oz numerous combinations of foam
profiles and porosities have been tested in harsh, dusty race conditions and
test tracks to come up with the ideal combination. With the assistance of
Australian KTM motocross and enduro race teams, more than 1,500 filters were
manufactured, tested and either serviced and reused, or cut open for inspection
before any were made available for sale. Australian Made the Funnel Web Filter is manufactured
by Infiltration Pty Ltd, an Australian owned company which has more than 30
years experience with foam filtration. All componentry and packaging are
Australian made and the product is assembled in our manufacturing facility in
Newcastle NSW.
