Yamaha Blow Off Valve & Intake Manifold Upgrade Kit
Description
Upgrade your Yamaha 1.8L Supercharged PWC with the Worx Racing Blow Off Valve Kit, now updated with a trumpet outlet for the best blow-off sound.
Designed to improve performance and reliability, this Yamaha 1.8 blow off valve features a larger valve for increased air dispersal, improved durability, and a sleek new design. The trumpet outlet delivers a crisp, aggressive blow-off sound while helping relieve excess boost pressure from the supercharger system.

The kit also includes our Intake Manifold Upgrade, allowing you to connect your breather line directly into the intake manifold without cutting hoses or making permanent modifications. Simply screw it in for a clean and easy installation.
Installing a Yamaha 1.8L blow off valve helps reduce stress on the supercharger clutch, improving longevity and reliability so you can spend more time riding and less time worrying about maintenance.
