What does the spring in a blow-off valve do?

The spring inside a blow-off valve holds the valve shut against boost pressure. It only allows the valve to open and release excess boost when the pressure in your intake system exceeds the spring's rated PSI, protecting your turbo.

How do I know if I need a different PSI spring?

If you've modified your turbo system and are experiencing boost leaks or overboost issues, or if you've changed your target boost pressure, you may need to swap to a different rated spring to match your new boost levels.

Does this spring come with a new blow-off valve?

No, this product is just the replacement 12 PSI spring for the TiAL Sport Q blow-off valve. You will need to already have the TiAL Sport Q BOV unit itself.

Product Details

This red 12 PSI spring is specifically made for the TiAL Sport Q blow-off valve. It's a key component that controls when your blow-off valve opens, which is crucial for protecting your turbocharger from overboost. The spring's tension determines the boost pressure at which the valve will release excess air, helping to prevent damage to your turbo and intercooler piping.

TiAL is known for well-built turbo components, and this spring is no exception. It's designed to work seamlessly with the Q model BOV, ensuring a reliable seal until the set boost pressure is reached. Swapping out springs is a common way to fine-tune your boost levels, especially if you've made other modifications to your engine's induction system. This red spring is rated for 12 PSI, making it a solid choice for many turbocharged applications looking for precise boost control.

When installing, make sure your blow-off valve is clean and free of debris. This spring is a direct replacement for the spring that came with your TiAL Sport Q BOV, and it fits right into place. Always refer to the manufacturer's instructions for the most accurate installation details.
