What does a wastegate spring do?

A wastegate spring controls the maximum boost pressure your turbocharger will produce. It works with the wastegate actuator to bypass exhaust gases around the turbine when a set pressure is reached, preventing over-boosting.

How do I know if this spring will fit my wastegate?

This spring is designed for standard and racing wastegates. It's best to consult your specific wastegate's documentation to confirm compatibility with aftermarket springs and the correct installation procedure.

What is the benefit of changing the wastegate spring?

Changing the wastegate spring allows you to adjust the target boost pressure for your turbocharged engine. This 10 PSI spring is suitable for applications seeking a moderate increase in boost over stock settings.

Product Details

This listing is for one HKS 10 PSI (0.7 Bar) yellow wastegate spring. This spring is designed to work with standard and racing wastegates to help regulate boost pressure in your turbocharged vehicle.

A wastegate spring's job is to control how much boost your turbocharger makes. By changing out the spring, you can adjust the maximum boost pressure your system will target. This particular spring is rated for 10 PSI, which is a common setting for modified turbocharged applications looking for a modest increase in boost over stock. The yellow color is an HKS identifier for this specific pressure rating.

When installing a new wastegate spring, it's important to ensure it's compatible with your existing wastegate actuator. Always refer to your wastegate manufacturer's installation instructions for the proper procedure.
