The Turbosmart Kompact Dual‑Port blow‑off valve for Ford Fiesta 1.0L EcoBoost vents both to atmosphere and back into the intake using two ports and sequential timing to balance sound and drivability. Under normal driving the sequential ports operate for quieter operation, while during aggressive or race conditions it benefits from vent‑to‑atmosphere release. This design offers the responsiveness of an atmospherically venting BOV while retaining smoother behavior on the street.
