Buying Guide for 2008 WRX Vacuum Line Kit with Restrictor

Understanding the Importance of Vacuum Lines

When I first started working on my 2008 WRX, I quickly learned that vacuum lines play a crucial role in the vehicle’s performance. These lines are responsible for controlling various engine functions, including the wastegate actuator, fuel pressure regulator, and more.
