YAMAHA SHO, FZR, FZS, GP1800/R/HO AIR FILTER
High Flow Filter design replaces the restrictive stock filter inside the OEM air box. This is the only performance filter that utilizes the water resistant OEM air box, allowing improved air flow. Why? Because replacing the OEM paper filter element with the high flow filter allows more air flow which equals more power and improved performance. The washable and reusable design means this will be the last filter you will ever have to buy.
