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) traps even the smallest particles, while the new, rounder design and minimized, micro-glued seams boost airflow more than ever.

For many years, Twin Air Factory Pre-Oiled filters were only available to our top professional race teams and OEM customers. Now everyone can get the same factory treatment: an Original Dual-Stage Air Filter is soaked in BIO Liquid Power Filter Oil, massaged to ensure all pores are evenly, cured in a temperature-controlled room, and sealed. You just open the resealable bag and install.

The best filter in the world can’t do its job if there are leaks in the seal of the airbox. Replace a flimsy, plastic stock cage with a Twin Air’s rigid, lightweight, billet-aluminum PowerFlow Kit to ensure a leak-proof, fool-proof fit. Custom design for each model ensures superior airflow, improved seal and easy service.

Fit this oiled, coarse foam pre-filter over your Twin Air filter for an extra layer of protection in severe conditions such as heavy dust and sand. Also extends service time between filter cleanings.

You’d be amazed at the dirt and debris that can work its way into your gas can – and from there, your fuel tank. Twin Air’s monofilament screen pocket inserts in your tank to catch particles as small as 40 microns (.00165”).

Twin Air MUD Deflector foam, no more mud hanging under the fenders! Deflector foam prevents the mud from sticking under the fenders, helping to eliminate added weight to the bike. The foam is pre-cut in bike specific dimensions and has a peel-off tape layer for easy mounting.
