TiAL Sport QRJ BOV 3 PSI Spring - Red (Excl Flanges)

This product is a red 3 PSI spring for the TiAL Sport QRJ blow-off valve. It's designed to replace the spring that comes standard with your QRJ BOV, allowing you to adjust the valve's opening pressure. You'll get the red 3 PSI spring itself, but remember that the actual blow-off valve and any necessary flanges are sold separately.

Swapping out the spring is a straightforward way to fine-tune your turbo system's performance. A lower spring pressure, like this 3 PSI option, means the blow-off valve will open sooner and more easily under boost. This can help reduce compressor surge, especially on smaller turbochargers or systems that don't build a lot of boost. The spring is well-built and intended for reliable operation in forced induction setups.

When installing this spring, make sure your QRJ blow-off valve is clean and free of debris. It's a good idea to refer to the TiAL Sport installation guide for your specific QRJ model to ensure proper assembly. Keep in mind this part is not CARB approved and cannot be shipped to California.
