The Kompact Dual Port blow-off valve is a direct replacement for the stock bypass valve on the Subaru WRX MY08-14 as well as the new Nissan Juke/Pulsar Turbo. Standard valves crack with age and heat cycling, and rely on rubber diaphragms which perish. They’re also simply not designed to handle increased boost levels. Turbosmart’s Kompact offers big blow-off valve performance in a small package. Its billet aluminium construction provides strength, while the precision-machined lightweight piston gives excellent valve response and sealing without relying on rubber diaphragms or O-rings, so it’s far more durable, and guards against compressor surge even when the boost is turned up.
