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.
In my opinion. When company’s take 6 months to ship an item they didn’t have that they said they did, they should send an email making sure you need it before shipping and do the honest thing and give the consumer the option to give the credit back as I already bought one.
I usually am more pro active to cancel but forgot about this one and it just showed up. Haha
