The Forge Abarth 500 Dump Valve is a high-performance replacement for the factory solenoid-driven valve. Unlike the OEM valve, which can leak over time or suffer from brittle plastic pistons, the Forge valve uses a billet aluminium piston for superior durability. As a result, it provides reliable operation, better throttle response, and the classic “whoosh” sound when the throttle is lifted.

Furthermore, the Forge valve retains ECU integration by diverting vacuum and boost pressure to the valve. Consequently, your engine management remains fully functional without triggering a check engine light, while allowing the valve to behave more like a traditional air-pressure-driven blow-off valve.

Key Features

• Dual piston design for long-lasting reliability

• Fully rebuildable and serviceable

• Configurable piston preload spring for different boost levels

• Retains ECU functionality with included solenoid and wiring harness

• Creates atmospheric “whoosh” sound for enhanced driving experience

• Improves throttle response and maintains boost pressure

• Limited lifetime warranty with proof of purchase

Why Choose the Forge Abarth 500 Dump Valve

Over time, OEM valves can leak or break due to brittle plastic components. In contrast, the Forge valve prevents these failures thanks to aluminium construction and dual pistons. Additionally, counterbalanced springs stop air leakage at idle, which single-piston or diaphragm valves often suffer from.

Moreover, the valve is easy to tune: you can adjust spring preload to match remapped engines or desired boost levels. As a result, it is suitable for both daily driving and high-performance applications.

Finally, the Forge valve kit comes complete with all necessary fittings, including a replacement solenoid and wiring harness, ensuring straightforward installation without compromising engine management.
