HKS Super Sequential Blow Off Valve kit for your Genesis Coupes Theta II Engine. This specially designed valve works with your Genesis Coupes turbocharged engine, and will offer you that unmistakeable sound offered by BOVs. The HKS redesigned Super Sequential Blow-Off Valve III (SSQV4)for the 2010 Hyundai Genesis Coupe Turbo is a high performance dual stage pull-type blow-off/bypass valve capable on any turbocharged performance level, from bone stock to fully track prepped. Unlike typical push type blow-off valves, the SSQV4 can not leak under any level of boost as it is designed to keep the valve closed against its seat when under boost. Many similar valves use a push-type valve design with a large valve to accommodate high boost and high horsepower applications.These large valves react slowly and require high pressure to open, and are not able to activate and prevent compressor surge at light-load conditions. On the other hand, smaller, fast reacting push-type valves do not discharge the airflow capacity required for high horsepower applications and tend to slowly open and leak as boost pressure overpowers the spring. For maximum performance, the SSQV4 incorporates both a small primary valve for ultra quick activation, and a larger secondary valve for additional discharge capacity. The SSQV4 is engineered to initially open the small primary valve at light throttle and load conditions, then sequentially opens the secondary valve for additional relief capacity under high boost and load conditions.

Complete kit is easy to install or remove. You will be able to switch your back to stock with our kit; everything is bolt on/off no cutting or welding.
