Product Description

The Turbosmart TS-0203-1210 Kompact Plumb-Back BOV is a compact, high-performance diverter valve designed for select Subaru WRX, Forester XT, Legacy GT, and the 1.6L turbo Nissan Juke/Pulsar. It replaces the weak OEM plastic bypass valves with a robust billet aluminum piston design capable of holding boost and running quieter due to full recirculation .

Installing this valve is simple and requires no modifications. It comes pre-fitted with a green spring ideal for street performance, but can be tuned with higher-rated springs for aggressive builds. While providing OEM-style quiet operation, it improves throttle response and boost consistency--even during lift-off--and fits snugly into tight engine bays thanks to the Kompact flange .

Note: This unit is race-use only and lacks CARB certification, making it unsuitable for street use in California. Confirm your vehicle make and model before ordering to ensure correct fitment.
