Product Description

The Go Fast Bits T9454 VTA Blow-Off Valve Kit is engineered exclusively for the 2012-2018 Ford Focus ST (Mk3) equipped with the 2.0 L EcoBoost turbocharged engine. Designed to replace the OEM electronic diverter valve, the VTA vents to atmosphere, providing that signature turbo blow-off sound while improving throttle responsiveness and boost recovery performance.

Utilizing GFB's patented Turbo Management System (TMS), the VTA retains factory ECU control and solenoid, delivering rapid boost response and preventing compressor surge under high-boost conditions. Constructed from precision CNC-machined aluminium, it offers long-lasting performance and reliability compared to OEM plastic diaphragms.

This kit installs easily using existing hardware, with no tuning or rewiring required. It offers a proven airflow upgrade for race and weekend builds, though it is not CARB-compliant and intended for off-road use only. Backed by GFB's lifetime warranty, the T9454 is a premium bolt-on upgrade for Focus ST enthusiasts.
