HKS Upgraded ACT Kit (R)PS13

HKS is well-known for making performance parts for Japanese sports cars. This upgraded actuator kit is designed to replace the stock unit on certain turbocharged vehicles. It helps manage boost pressure more precisely, which can lead to a more consistent power delivery from your turbocharger.

This kit includes a stronger spring and a more robust actuator arm compared to the factory part. The goal here is to prevent boost creep, where the turbocharger produces more boost than the engine management system is set to handle, especially as the turbo spools up. By using a well-built actuator, you can help ensure your turbo stays within its intended operating range, contributing to smoother acceleration and better overall performance.

Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and setup.
