The Turbosmart Kompact Dual-Port blow-off valve for Ford EcoBoost 1.6L applications vents both to atmosphere and back into the intake. Its dual ports use sequential timing for quieter operation during normal driving while still providing vent-to-atmosphere release under race conditions, giving a compromise between stealthy daily manners and open-throttle sound and response when pushed.
