View Full Version : Aluminum check valves

Found some Aluminum check valves, and remembered i have yet to replace said check valves on my current A4. They come in 6, 8, 10, and 12mm from what i can see on this site. Even cheaper then after market plastic ones off ECS as well.



Anyone know off hand the size we would need for a b5? Thinking about grabbing some when i re do all my vacuum lines with black silicone...
