As an essential part Subaru makes the WRX STI PCV Valve an emblem of their dedication to both dependability and peak performance output. The PCV Valve executes its design by transporting partially burned gases from the crankcase to the combustion chambers for improved efficiency and minimal emission production. Through its two-faceted protective action the valve safeguards both environmental systems alongside maintaining continuous engine performance and stopping the formation of waste oil sludge deposits. All gas flow control for the Subaru WRX STI PCV Valve occurs through intake manifold vacuum to maintain peak engine performance parameters.

Routine maintenance of the PCV Valve ensures both high performance and optimal efficiency levels of the vehicle. The Subaru WRX STI achieves excellent market position as a leading performance car because of this vital component which powers its sport compact construction and 300-hp turbocharged engine.
