TWIN AIR Air Filter - fits stock airbox and Speedwerx High Flow Air Intake

TWIN AIR’s breakthrough, fused-dual-layer design (now widely copied) combined performance and protection. The fused layers of open-pore foam and fine inner foam trap even the smallest particles. The new, rounder design boosts airflow. So do the minimized seams made possible by a revolutionary micro-gluing process: Shorter seams = more foam = more flow.

  • WASHABLE / REUSABLE (reusing a TWIN AIR filter 40-50 times is common)
  • DUAL-LAYER FOAM (made to our specifications, with cells that are evenly sized and distributed)
  • PRE-OILED and ready to install
  • HIGH QUALITY (assembled by hand and inspected for a perfect fit)

In some respects, motocross was born in the Netherlands.

It was here, in 1947, that the Dutch national motorcycle federation hosted an international “scramble” for teams from Great Britain, Belgium and the Netherlands, and called it a “moto-cross.” While the sport’s popularity grew steadily over the next 25 years, one thing that remained constant was the frustration of off-road biking in the Netherlands. The lowland dunes and fields offered the perfect terrain for riding, but the stock paper air filters of the day were no match for the sandy, gritty soil. There was a paper filter with a single layer of foam, but even that didn’t cut it for protection; after 30 minutes it was shot.

In 1972, the motocross world was given a historic boost by a revolutionary product: a laminated, dual-foam air filter that, when soaked in a special oil, allowed free airflow into the carburetor while keeping dirt, grime, sand and water out of it. It was effective, durable, washable and reusable. It took off, and the little start-up company that invented it, called Twin Air, hasn’t stopped ever since.

Evolving continually with motorcycle design and technology, Twin Air filters and accessories have stayed ahead of the competition for half a century. Today they are available for all Motocross and ATV vehicles, and distributed worldwide. Twin Air filters are OEM-specified for 20+ motorcycle companies, and the official air filter of American Honda and Suzuki, Kawasaki Racing Team, Suzuki Geboers, Honda Martin and Honda CAS, KTM Red Bull, and many other teams. It remains the choice of more World & National Champions than all other filters combined.
