Why buy the Forge Fiat 500 dump valve?
Your Fiat 500 is equipped with an electronic solenoid driven valve from the factory, which is integrated into the functions of the ECU, and unplugging or removing the valve will result in a check engine light on the dashboard.
The Forge solution is to retain the solenoid operation, but to use it to divert vacuum and boost pressure to the valve, to make it into a more traditional valve driven by air pressure. The Forge valve will give you a product that is superior in its construction and durability over the OEM valve, and of course the forge is serviceable and guaranteed for life .
Over time the OEM valve begins to leak, and in some cases the plastic piston goes brittle and breaks.
The Forge valve doesn’t suffer with either of these problems as it uses an aluminium piston and is totally rebuildable. It’s also configurable for different levels of boost pressure e.g. on a remapped car, by simply changing the piston preload spring inside the valve.
Go fit the Forge Fiat valve and enjoy the performance.
