Product Details

This product is a 3 PSI spring for the TiAL Sport QRJ blow-off valve, finished in silver. It's designed to replace the spring that came with your existing QRJ BOV, allowing you to change the pressure at which the valve opens to vent excess boost. This is a well-built component from TiAL Sport, a popular name in the forced induction world.

Adjusting the opening pressure of your blow-off valve is important for proper boost control. The stock spring in your QRJ BOV is set to a specific pressure, and if your engine's boost levels are lower or higher than that setting, you might experience issues like boost leaks or premature valve opening. Swapping to this 3 PSI spring lets you fine-tune the BOV's operation to better match your turbo system's boost output. Remember that this spring is sold without the flanges, so you'll need to reuse your existing QRJ BOV flanges.

Please note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and to ensure compatibility with your specific turbo setup.
