The GFB VTA blow-off valve for 2016+ Ford Focus RS vents to atmosphere to produce the characteristic turbo blow-off sound while replacing weaker factory internals for improved strength and reliability in high-boost use. The VTA range is engineered for application-specific fit and maintains solenoid and ECU control where a factory solenoid is present, delivering faster boost recovery and improved boost holding.
