AMSOIL Twin Air Dual-Stage Powersports Filters


Company History

Twin Air USA is the exclusive importer, marketer and promoter for Twin Air products in the United States. The company was founded in the Netherlands more than 30 years ago, where the sandy, gritty soil was destroying stock paper air filters and causing big problems for engines. Twin Air developed the solution with its special laminated foam air filters and filter accessories. Today, Twin Air remains at the forefront of powersports filtration technology, making it a perfect partner for AMSOIL. Twin Air is the OEM filter supplier to more than 10 motorcycle companies and manufactures the best-selling off-road air filter in the world.

Solid Construction

Twin Air filters are constructed from two layers of openpore foam that are bonded together to provide maximum filtration and superior airflow. A coarse-foam outer shell is fused with a fine-foam inner core, resulting in a one-piece design that is both functional and durable. It provides continuous filtration and airflow while protecting engines from dirt, dust and sand.

The Twin Air Advantage

Twin Air air filtration products provide dirtbikes and ATVs with maximum intake protection in any riding conditions. The coarse open-pore foam catches airborne dirt, grime and sand, while the fine open-pore inner foam acts as a second filter to trap the smallest particles while ensuring maximum air passage. Twin Air air filters are constructed with an exclusively formulated adhesive that withstands repeated cleanings, even with harsh solvents or gasoline. Their thick, flat-foam greaseless sealing ring ensures maximum contact with the airbox while acting as a breathable gasket for increased air passage.

Twin Air’s patented filtration design, high-quality materials and superior construction deliver maximum performance and protection. Consult the Online Powersports Application Guide for application information.

Cleaning Products

AMSOIL also offers several Twin Air filter cleaning and oiling products. AMSOIL will continue to offer AMSOIL High Tack Foam Filter Oil (AFO) and Foam Filter Cleaner (FFC), which perform well with Twin Air Filters. AMSOIL, however, wanted to provide all Twin Air products, including oils and cleaners, for Dealers and customers to have a consistent and compatible product line. In addition, Twin Air offers biodegradable products that are popular in this market. Buy Maintenance Products
