TWIN AIR AIR FILTER YAMAHA YFZ 450 (2004-2025)

Twin Air Filter's design, high quality materials and superior construction deliver unbeatable performance and protection - and make Twin Air Filters the hands-down choice of more World & National Champions than all other filters combined. Coarse open-pore foam catches airborne dirt, grime and sand. Fine open-pore inner foam acts as a second filter to trap the smallest particles while ensuring maximum air passage. Exclusively formulated adhesive ensures glue seams will not break down. Thick, flat foam, greaseless sealing ring ensures maximum contact with your airbox, while acting as a breathable gasket for increased air passage. Fused outer and inner elements prevent dirt and grime from being lodged between layers, unlike Twin Air, this can be a problem with inferior two-piece designs. Trapped particles can restrict airflow. And if dirt works it's way into your engine, a pinhead-sized granule will gouge your cylinder, piston and rings like a bullet. Used Pre-Oiled Air Filter. The coarse outer Shell catches airborne dirt, grime and sand. The fine inner layer traps the little stuff. Twin Air filters are designed to increase airflow while ensuring the highest level of protection from dirt/dust.

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.
