The Turbo XS Type XS recirculating bypass valve fits 2015–2021 Subaru WRX applications and comes in a red/silver finish. Functioning as a recirculating blow‑off valve, it vents boost back into the intake tract when the throttle closes, providing a serviceable, vehicle‑specific upgrade for WRX turbo systems that prefer closed‑loop bypass behavior over atmosphere dump styles.
