GReddy 11521212 Blow Off Valve FV2: 89-93 Nissan Skyline GT-S HCR32 RB20DET

The GReddy Blow Off Valve FV2 inherits the floating valve structure that was popular in the previous model, while improving upon the sophisticated design, maintainability, and reliability. A rotating knob that enables the preload adjustment of the spring without tools is adopted, and the direction of the vacuum hose nipple can be adjusted 360 degrees without the use of tools as well. An updated funnel outlet design provides a more aggressive look over the previous model. The mounting flange and opening have the same dimensions as the GReddy Blow Off Valve Type RS, RZ, and FV, so retro-fitting to existing applications is possible. 100% genuine GReddy product. Part# 11521212 / BFV2-209. Made by GReddy / TRUST Japan.

Prevents idling problems that tend to occur with blow-off
*The floating valve mechanism allows the valve to react quickly because there is no need to apply unnecessary preload to the spring.

Quick response even at low boost
*The floating valve mechanism prevents unnecessary opening and closing of the valve.

Uses a floating valve structure
*By adopting a floating valve structure in which the diaphragm and valve operate independently, it is possible to achieve a valve response that exceeds that of the conventional model and a stable blow-off effect in the entire boost range.
