The best filter in the world can't do its job if there are leaks in the seal of the airbox. That's why Twin Air provides a complete line of products to ensure a leak-proof, fool proof fit. Twin Air's PowerFlow kit comes with a rigid, lightweight, billet aluminum cage that provides a tight seal to the airbox and replaces your flimsy plastic stock cage.

A Twin Air Powerflow Kit includes a pre-oiled Twin Air filter, a special aluminum cage and all necessary mounting hardware.

PowerFlow Kits for ATVs are custom-designed to each unique application for superior airflow, improved sealing surface, removal of the restrictive backfire screen, and ease of service.

About Twin Air

In some respects, International Motocross was born in the Netherlands. As the sport of Motocross grew in popularity over the next 25 years, it became clear that the air-filter technology of the day was inadequate. The filter itself was made of paper with a single layer of foam and could not provide sufficient protection from the sandy riding conditions in the dunes and fields of the Netherlands.

In 1972, the Motocross world was given a historic boost by a revolutionary new product: a flame laminated, dual-stage foam air filter that, when soaked in a special oil, allowed free airflow into the carburetor while providing the engine maximum protection from particles of sand, grime and water. It was not only effective, but durable, washable and reusable. The new inventive product became the beginning of the company Twin Air.

Twin Air is today a renowned brand name and the company's product line is continually evolving and expanding. The technology and design of Twin Air filters and accessories have stayed ahead of the competition for nearly half a century and are OEM-specified to more than 30 motorcycle companies worldwide.

Next to Twin Air filters, there is also a complete line of filter care products and upgrades for improved bike performance. Twin Air USA is our importer for the Americas and together with a worldwide network of  distributors, Twin Air products are available around the globe. Since 1972, Twin Air supported over 300 World Champions and Twin Air supported teams and riders participate in World Championships around the world.
