Twin Air's legendary quality heralds back more then 40 years when stock paper air filters were a big problem for the engine especially in the sandy, gritty soil of The Netherlands. Single foam and paper filters gave riders airflow, but didn't cut it for protection and lasted only 30 minutes in the sand dunes of Holland. Twin Air found the solution to deliver unbeatable performance and protection by producing special laminated Foam air filters and filter accessories. The original typical Paper air filter was consequently replaced by washable Twin Air foam air filters. These Twin Air filters are, when treated with the right filter oil, a perfect product to prevent dirt, grime, sand and water entering the carburettor and giving unbeatable performance. Now Twin Air is known because of it's superior quality, craftsmanship, supplying and service of foam air filters with a very large distribution network all over the world. Twin Air is the choice of more World and National Champions than all other airfilters combined. Twin Air has provided the greatest names in motocross with performance and protection; Ryan Dungey, Ricky Carmichael, Stefan Everts (10-times world champion), Roger DeCoster, Eric Geboers, Jeremy McGrath, Kevin Windham, David Thorpe, Travis Patrana, Jean Michel Bayle, Greg Albertyn and Scott Summers to mention just a few.
