Open-type blow-off valve kit for replacing the factory one for Fiat Punto-500 Abarth and Alfa Romeo Mito, Giulietta with Multi Air engine.

The factory blow-off valve on these engines has pressure loss when it is programmed to work with increased turbo pressure.

The Forge motorsport blow-off valve contains a piston instead of a diaphragm for immediate and trouble-free operation and stable pressure on repeated throttle presses.

For various stages of improvement, there is the option to select spring stiffness depending on the turbo pressure.

The kit includes all additional components (solenoid valve, hoses, etc.) for trouble-free installation and comes with detailed installation instructions.
