Twin Air PowerFlow Kit upgrades your intake with a leak-proof sealing surface and improved airflow, so your engine gets clean air without airbox bypass. The kit includes a BIO Factory pre-oiled, washable dual-layer foam filter plus a rigid aluminum cage for a secure, fool-proof fit.
Upgrade your air intake sealing and airflow with the Twin Air PowerFlow Kit. Even the best air filter can’t protect your engine if the airbox seal leaks—dust and grit can bypass the filter and cause unnecessary wear. PowerFlow Kits are designed to create a more reliable, leak-proof interface between the filter and airbox while also improving airflow and making servicing faster and easier.
Each kit is application-specific and combines a high-quality Twin Air foam filter with a rigid, lightweight aluminum cage that replaces the typical flimsy stock plastic cage. Depending on the bike, the kit may also include a billet-aluminum flange that bolts tightly to the airbox for a more consistent sealing surface. For certain 4-stroke applications, the kit replaces the restrictive backfire screen with a redesigned solution featuring a special backfire-resistant foam layer.
