This is where it all began. Over 40 years ago, the sandy, gritty soil of The Netherlands - and the resulting engine failures - proved that single-foam and paper filters gave riders air flow, but failed at protection. 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.
- Twin Air filters are designed to increase airflow while ensuring the highest level of protection from dirt / dust.
- Washable / reusable - reusing a Twin Air filter 40 - 50 times is common.
- High quality - assembled by hand and inspected for a perfect fit.
- 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.
- Filter includes a filter cage or plastic spacer.
- Twin Air filters are slightly smaller than stock to make them easier to change and to increase dead air space around the filter for better performance.
