The Pyramid Foam
FunnelWeb’s profile cut foam effectively doubles the filters external surface area, without increasing the filters original size, enabling it to trap and hold far more dust on the outer surface. This means more protection to the engine while maintaining optimal airflow and extending filter service intervals.
The Filter Seal
Most FunnelWeb Filter seals are constructed from injection molded urethane for a lasting, precise fit on the filter support frame and the inside of the air box. Foam seals, as fitted to other filter brands, will tend to stretch out of shape after a few cleans resulting in a poor fit to the support frame, possibly affecting the filters sealing ability.
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.
The FunnelWeb 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.
