Riva Racing's performance blow-off valve kit improves supercharger reliability and performance by relieving unwanted pressure during off-throttle operation.
It reduces supercharger clutch and gear wear, eliminating heat soak in the discharge tube.
The high-strength silicone hose with integrated HKS valve installs easily in place of OEM elbow joint.
This kit includes a HKS Super SQV (Super Sequential Blow-off Valve) that features unique sequential valve structure and a differential pressure control system, allowing for a broad operation boost range.
Also includes a vacuum line and all fittings required for installation on Yamaha SHO and SVHO engines.
A simple and cost effective upgrade for both stock and modified engines running the original intercooler.
