Funnelweb Filters

FunnelWeb Filters

The Build

The FunnelWeb Filter was designed and manufactured by Infiltration Pty Ltd, an Australian Company with more than 40 years of experience in off-road motorcycle foam air filtration within the organization. FunnelWeb Filters are manufactured utilizing the latest technologies in open cell foam 3D profiling.

Their pyramid profile effectively doubles the filters outside surface area without increasing its overall size and, compared with conventional foam air filters, has been designed to:

  • Trap and hold more dust on the outside surface of the filter.
  • Maintain optimal airflow by spreading dust built over an increased surface area.
  • Enable longer filter service intervals.

Most 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, these air filters have proven extremely effective in protecting high-performance motorcycle engines in the harshest off-road racing conditions worldwide.

The Foam

The pyramid foam profile effectively doubles the outside surface area without increasing the filter's overall size. The company believes foam air filters should be 'surface loading.' That is, the ability to trap as much dust on the oiled filters outside the surface where it is visible. Two-stage filters allow fine dust to penetrate the coarse outer layer and deep into the body of the filter where it can't be seen.

FunnelWeb filter foam will:

  • Provide a 100% larger surface to trap more dust.
  • Trap dust evenly over the increased outside surface area while allowing optimum airflow for longer periods of riding.
  • Effectively reduce 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 molded 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, where they use die-cut polyurethane foam to do the job.
