Description
This precision-machined whistle accessory transforms the factory vent-to-atmosphere (VTA) outlet on Ford EcoBoost engines into a distinct, high-pitched whistle when the valve vents, adding audible feedback without altering the turbo system internals. Designed by GFB to complement existing VTA installations, the whistling trumpet provides an unmistakable sound signature for EcoBoost owners who want a sporty, attention-grabbing exhaust of boost pressure while retaining the vehicle’s original blow-off valve functionality.
