Description
Experience sharper throttle response and the unmistakable turbo "whoosh" with the Forge Motorsport Twin Piston Blow Off Valve with Side Vacuum Nipple (FMDV004A). Designed for performance and space efficiency, this valve is ideal for turbocharged applications where engine bay clearance is limited.
Constructed from high-quality billet aluminum, this atmospheric diverter valve vents excess boost pressure to the atmosphere upon throttle lift, enhancing both responsiveness and driving excitement. The innovative twin-piston design uses counterbalanced springs to maintain a secure seal at idle and prevent boost leaks—something single piston or diaphragm-type valves often struggle with.
Unlike traditional valves that recirculate air into the intake, Forge's atmospheric system releases unused boost to the environment, delivering a crisp and aggressive turbo sound. This design is engineered to improve reliability and performance, particularly under demanding conditions.
Key Features:
-
Twin-piston construction ensures superior reliability and leak-free operation at idle
-
Side-mounted vacuum nipple allows easy installation in space-restricted engine bays
-
Produces the signature atmospheric turbo "whoosh" sound
-
Enhances throttle response and maintains boost pressure more effectively
-
CNC-machined from durable billet aluminum
-
Universal fitment for most turbocharged vehicles equipped with an air flow meter
-
Recommended service interval: Every 3 years or 20,000 miles (whichever comes first)
Fitment Notes:
This valve is designed for universal applications and is compatible with most turbocharged engines equipped with mass air flow (MAF) sensors. While Forge Motorsport has engineered this valve to work with a wide range of systems, compatibility with specific vehicles may vary based on ECU sensitivity and air metering strategy.
Important Disclaimer:
This is a vent-to-atmosphere valve and may not be suitable for all vehicles—particularly those with sensitive engine management systems not designed to accommodate unmetered airflow. Forge Motorsport and its distributors are not responsible for any adverse engine behavior caused by incompatible setups. Please consult with us prior to purchase if you're unsure of fitment.
