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

This boost pressure relief valve (BOV) is an essential pressure-regulating device on the intake system, designed to protect the turbocharger compressor from surging. It uses a clever combination of the intake pressure signal and spring force to detect when the throttle valve closes. When the throttle closes rapidly, the valve instantly vents excess pressure from the intake system to the atmosphere, eliminating pressure fluctuations and surging that could eventually damage the thrust bearing due to the high loads it generates. Our model stands out for its performance and robustness. It features a dual-spring system that optimizes responsiveness and can withstand boost pressures of up to 30 PSI. For increased airflow and maximum durability, it incorporates a 40 mm hard-anodized valve. Its 8-port exhaust design draws in ambient air to produce a characteristic and aggressive exhaust note, typical of the JDM and racing world. Installation is simplified thanks to its 2-hole mounting design. The product is made of aluminum and corresponds to OEM part numbers SDD-BOVGRSBL and FPG250. The flange tube diameter is approximately 2.5 inches (6.4 cm). This decompression valve is compatible with TYPE-S and TYPE-R dump pipe flanges.
