Parts required for Install
The factory overflow tank will need to be removed and replaced with the Cobb Tuning low profile coolant overflow tank. This will provide adequate clearance for the cold side piping.
Remove the two foam pads from the sides of the core support with a plastic clip removal tool.
With the intercooler now in place, it's time to mock up the lower hot and cold pipes and carefully trim the under tray and inner fender liners to provide clearance for the intercooler pipes.
With the core installed and the necessary trimming to the fender liners and under tray done, it's now time to install the piping. For this step you can remove the under tray again.
The cold side intercooler piping will install in similar fashion as the hot side.
With all the new intercooler components in place, it's time to clearance the bumper cover to fit over the new front mounted core. These instructions are a general guideline as every install will be slightly different. There are a variety of tools one can use to accomplish this task, choose the one that you feel most comfortable with. The following steps are a quick overview of what trimming needs to take place. Go slowly. Be conservative. It's a lot easier to remove a little more than add material back in.
