Preparation Steps

Before you begin the installation, it’s important to prepare your vehicle properly. Follow these steps to ensure a safe working environment:

  • Disconnect the O2 sensor wiring harness by gently pulling it apart.
  • Unbolt the downpipe from the exhaust system, ensuring all connections are free.
