Forge Motorsport Atmospheric Blow Off Valve for Audi S4 B9 and Audi S5 B9
The Forge Motorsport Atmospheric Blow Off Valve is a high-performance upgrade designed specifically for the Audi S4 B9 and Audi S5 B9 models. This solenoid operated valve seamlessly integrates with the OEM electronics, ensuring no-fault codes, check engine lights, or negative impact on vehicle performance.
Unlike the OEM solenoid valves that are prone to failure, the Forge Motorsport valve is built with full billet alloy construction and a piston-based internal design. This provides superior reliability, lightning-fast response, and the ability to withstand additional tuning upgrades. Say goodbye to boost leaks caused by diaphragm or plastic piston failures.
The package includes the FMDV13 Valve, wiring harness, solenoid, bracket, screws, blue uprated spring, cable ties, 2000mm length of 4mm vacuum hose, instructions, Forge keyring, and sticker.
