Using the COBB Fuel Rail Line Kit is straightforward. First, make sure your vehicle is a 2008 - 2021 Subaru STI. The kit is designed to be used with the COBB Fuel Rail Kit, so have that ready as well. All the lines are pre - assembled, which means you can start the installation right away. However, note that the installation instructions can be a bit difficult, so take your time and follow them carefully. When installing, keep in mind the 3' minimum bend radius of the lines to ensure a proper fit. For maintenance, regularly check the lines for any signs of wear or damage.
