2.5-inch billet aluminum turbo relief valve, universal type SDDBOVGRSBL FPG250 (purple)

The blow-off valve (BOV) is a pressure-regulating device on the intake system, designed to prevent the turbocharger compressor from surging. It uses a combination of intake pressure signal and spring force to detect when the throttle valves close. When these close rapidly, the BOV vents excess pressure from the intake system to the atmosphere, eliminating the risk of surging and harmful pressure fluctuations that can eventually damage the thrust bearings. Our model features eight blow-off ports that draw in ambient air to produce a distinctive, aggressive, and recognizable JDM racing exhaust note. It is equipped with a dual-spring system for optimized response and boost pressure handling up to 30 PSI. Its installation is facilitated by a 2-bolt design, and it incorporates a 40mm hard-anodized valve for increased airflow.
