Forge Motorsport FMDVF500A Open Dump Valve for Fiat 500 Abarth T-Jet

Why buy the Forge blow-off valve for the Fiat 500? Your Fiat 500 comes factory-equipped with a solenoid valve integrated into the ECU. If you disconnect or remove it, the engine warning light will illuminate on the dashboard.

The Forge solution maintains the solenoid valve's operation but uses it to divert vacuum and boost pressure to the valve, turning it into a more traditional compressed air-actuated valve. The Forge valve offers a superior product in construction and durability compared to the original valve. Furthermore, it is serviceable and comes with a lifetime warranty.

The Forge valve does not exhibit any of these problems, as it uses an aluminum piston and is fully serviceable. It is also configurable for different boost pressure levels, for example, in a remapped vehicle, simply by changing the piston's preload spring. The Forge open-loop blow-off valve for Fiat 500 Abarth T-Jet is made of aluminum. This open-loop blow-off valve vents pressure to the atmosphere, producing the famous "Pschhht" sound when lifting off the throttle. This improves throttle response and optimizes sealing for greater reliability. Unlike single-piston or diaphragm blow-off valves, this one uses counterbalanced springs and a double piston to prevent air leaks into the intake system at idle. This prevents piston or diaphragm failure issues in Forge's open-loop blow-off valves.
The kit includes all fasteners, a solenoid, and a harness connector to maintain the engine management system's functionality. The blow-off valve features a double piston design for increased durability, and it is also fully disassemblable and easily adjustable with replacement springs if needed.
