Designed specifically for 2013–2018 Focus ST models, this system uses a custom throttle body injection plate for a clean, direct installation at the throttle body. As boost rises, the VC-50 progressively increases injection to help lower intake temperatures, clean carbon buildup, and support more aggressive tuning on pump gas.
The complete setup includes braided stainless line, 4AN fittings, a 300 PSI pump, dual Hyper-Sonic™ nozzles, a 2.5-gallon trunk-mounted tank, and the VC-50 controller with built-in boost display, adjustable injection settings, system monitoring, and selectable screen colors.
More cooling when the engine needs it. More control over how the system responds. More potential from your Focus ST.
Made in the USA.
