About FunnelWeb Filter

You may not have heard of us but we have been involved in the Australian Off Road Racing Industry for several years, developing what we believe to be a vastly improved foam air filter.

The FunnelWeb Filter was designed, and is manufactured, by Infiltration Pty Ltd, an Australian owned company with over 30 years experience with foam filtration within the organization.

Foam air filters have been used in off road motorcycles for nearly four decades and are now standard equipment in the vast majority of off-road motorcycles worldwide.

The foam filter's basic design has had little change since its inception so we decided to do something about it.

We have utilized the latest technologies in open cell polyurethane foam profiling to substantially increase the filter's surface area, not only offering more protection, but enabling the filter to last longer before cleaning and reoiling.

Tough, injection molded urethane seals were chosen for a precise fit, positive seal and strength on most of the range, whilst flexible neoprene seals are fitted on some filters including the Minibike range.

Over the years, close to two thousand filters have been tested in some of the harshest conditions imaginable to give us the confidence in putting FunnelWeb to market.

With the invaluable assistance of the Motorex KTM Off-Road and JDR KTM Factory Racing teams we have been fortunate to be able to utilize the best test beds available: the race track.

Along the way the FunnelWeb Filters have been fitted to the KTM race bikes and played a small part in their many race victories and Australian Championships.
