Yamaha FX-HO FX140 2004-2008 MR-1 RIVA Power Filter Kit - ADD MPH+ RY1325-1 NEW

YAMAHA RIVA FX-HO Power Filter Kit

Fits: ALL FX/ FX-HO & FX-140 Models

Our FX Power Filter® is a direct replacement for the restrictive stock air filter in the OEM air box. Delivers increased airflow to engine providing improved throttle response, acceleration and top speed. Screen-type element will not soak up excess engine oil as does the OEM paper element that increasingly restricts performance.

NOTE: Power Filter required when using RIVA FX Velocity Stacks (part# RY1325-VSK) to meet U.S. Coast Guard flame arrestor requirements.
