Blow Off Valve for Subaru
Plumb Back Blue
Fits for: Subaru all WRX from 01-07, Sti 01-, Forester 05-07
The housing is CNC milled from solid aluminium. The result is particularly small and lightweight valves that can withstand extreme conditions. The Blow Off valves are supplied with a V-band clamp to permanently secure it and at the same time quick fastening. In contrast to other valves with plastic diaphragms, these valves are equipped with a precisely manufactured piston that fits intake into the inside of the housing. This eliminates the risk of these valves starting to leak after a short time. Due to minimal production tolerances, no O-ring is required to seal the piston, making these blow-off valves extremely robust, low maintenance and reliable.
The Plumb Back valve is a bypass valve - it returns all the air back into the air intake duct. This makes this valve particularly suitable as a high-quality replacement for a standard valve with plastic diaphragm, which often 'leaks', causing a loss of performance at the same time.
