WORX Yamaha Blow Off Valve Kit for Supercharged 1.8L Yamaha (2008-2026) - WR04021-69
This Yamaha blow off valve kit is built for supercharged 1.8L Yamaha PWC applications and helps relieve intake pressure during throttle changes. It fits select Yamaha FX, GP, FZR, and FZS models and is designed to improve air management while helping reduce load on the supercharger clutch system.
This kit uses a larger valve for better air dispersal and includes a trumpet outlet for blow-off sound. It is a simple intake-side upgrade for riders who want better pressure relief on the supercharged 1.8L Yamaha platform without changing the full intake system. WORX states this kit greatly improves supercharger clutch life on the correct applications, making it a practical upgrade for riders who want better pressure control during on-off throttle transitions.
The supplied parts include the WORX blow off valve unit, WORX silicone blow off valve hose, 1m BOV hose line, 1.5 inch hose clamp, T piece hose fitting, and 10 zip ties. Installation replaces the stock intake hose tube using the OEM clamps, and the hose line routes to the MAP line sensor with the supplied T piece. WORX lists this as a 5-minute installation. Tools required are a 7mm socket wrench, Phillips head screwdriver, and side cutters.
Colors offered by WORX include Stealth Black, Nitro Blue, and Race Red. Does not fit non-supercharged Yamaha models including FX HO, GP HO, VX, EX. Does not fit models not listed below.
