TiAL Sport QRJ BOV 1.5 PSI Spring - Red

This is the 1.5 PSI red spring for the TiAL Sport QRJ blow-off valve. The spring's tension is what keeps the valve sealed against boost pressure. A lower tension spring, like this 1.5 PSI version, means the valve will open sooner under boost, which can be useful for certain engine setups or tuning strategies. It's a direct replacement for the spring that came with your QRJ valve, allowing you to fine-tune its operation.

TiAL Sport is known for making well-built components for turbocharged vehicles. This spring is made to the same specifications as the original, ensuring it works correctly with your QRJ blow-off valve. Swapping springs is a straightforward way to adjust how your blow-off valve responds to boost pressure. If you're looking to change the opening point of your existing TiAL QRJ BOV, this spring is the part you need.
