Type-RS Blow-Off Valve

It utilizes a unique floating valve structure that remains closed under negative intake manifold pressure, preventing unintended valve actuation and associated idling issues. This design contributes to a quick response even in low boost conditions, while effectively preventing boost relief under high-pressure situations. Constructed with a focus on user-friendliness and reliability, the Type FV features a gunmetal/blue finish and an adjustable detent rotary knob for tool-free preload spring adjustment. The top hat is also 360-degree adjustable without disassembly, allowing for flexible vacuum fitting orientation. The valve's mounting flange and inlet dimensions are identical to previous GReddy blow-off valves (TYPE-RS, RZ, and FV), facilitating a direct replacement for older models. This valve is rated for an 80-480hp range and is manufactured in Japan. Included in the box are the blow-off valve, mounting hardware, and a vacuum nipple. The GReddy Type FV Blow-Off Valve is a universal application, designed to be compatible with standard 2-bolt GReddy BOV flanges and Type-RZ outlet adapters. It is backed by GReddy's Limited Manufacturer's Warranty.
