Description
Enhance the performance, reliability, and sound of your Audi RS4 or RS5 B9 (2.9L twin-turbo V6) with the Forge Motorsport Atmospheric Dump Valve Kit. This premium upgrade is engineered to replace the OEM solenoid valves, which are known to suffer from diaphragm failure—leading to unwanted boost leaks and decreased turbo efficiency.
Forge's solution uses precision CNC-machined billet aluminum construction paired with a piston-based internal design for lightning-fast response and long-term durability. Unlike the factory valves, these are built to handle increased boost levels and spirited driving without failure.
Designed as a complete plug-and-play solution, this kit includes a custom wiring harness that seamlessly integrates with your OEM electronics. You’ll experience no check engine lights, no fault codes, and zero impact on drivability—just sharp turbo response and the aggressive blow-off sound enthusiasts love.
