Turbosmart TS-0203-1015 Kompact Dual Port Blow Off Valve for Subaru Forester XT WRX STI

Dual Port blow-off valve. The Kompact Dual Port vents to both the atmosphere and back into the air intake. Sequentially timed ports allow for quiet operation during normal driving, while still offering the performance and sound of an atmospheric venting blow-off valve when the going gets tough. The standard blow-off valves on these cars are plastic, unlike the Kompact’s high-durability machined aluminum construction. Standard valves are often unable to remove damaging compressor surge, and over time, the plastic becomes brittle and can crack, causing significant pressure leaks. This prevents the turbo from reaching its full potential, sapping performance. With its machined anodized aluminum body and light alloy piston, the Kompact provides extreme durability, superior response, and excellent pressure-holding capabilities for its size. The Kompact Dual Port is perfect for owners of standard or lightly modified cars looking for that classic atmospheric venting blow-off valve sound in a compact, factory-replacement package.
