The FunnelWeb Filter was designed and is manufactured by Infiltration Pty Ltd, an Australian Company with more than 40 years of experience in offroad motorcycle foam air filtration within the organization.
FunnelWeb Filters are manufactured utilizing the latest technologies in open cell foam 3D profiling.
The pyramid profile effectively doubles the filters outside surface area without increasing its overall size and, compared with conventional foam air filters, have been designed to:
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.
A majority of FunnelWeb Filters are manufactured with a urethane/foam combination seal for strength and longevity. These filter seals will not shrink, stretch or tear and will maintain their shape, regardless of how they are treated.
They are designed to provide an ongoing positive seal to the air box, ensuring any air entering the engine passes through the oiled filter foam.
Over the last decade FunnelWeb air filters have proven to be extremely effective in protecting high performance motorcycle engines in the harshest off road racing conditions worldwide.
