Turbosmart WG 38/40/45 HP 10 PSI Inner Spring Brown / Orange

This package includes one Turbosmart 10 PSI inner wastegate spring, color-coded brown/orange. This spring is designed for use with Turbosmart WG 38, 40, and 45 external wastegates.

Changing the inner spring is a common way to adjust boost pressure on turbocharged vehicles. A stiffer spring, like this 10 PSI option, will require more exhaust pressure to open the wastegate, allowing the turbocharger to build more boost before the wastegate bypasses exhaust gas. This spring is a well-built component for fine-tuning your forced induction setup.

If you're looking to increase boost pressure on your turbocharged vehicle and have a compatible Turbosmart wastegate, this inner spring is a straightforward way to achieve it. Always ensure your engine management system is tuned to handle the increased boost levels.
