The original bumper beam needs to be replaced with the Cobb bumper beam to allow room for the new intercooler core.
Feed the bent end of the hot side pipe up though the fender into the hole where the factory intake once was (blue arrow.) The rubber isolator will align with a small hole in the fender between the two intake holes in the fender. Hand tighten the other 6MM flange nut on the stud that comes though the fender (yellow arrow.)
In order to properly fit the COBB FMIC, the COBB SF Airbox (if installed) must be trimmed. Please print the following attachment in full size and in landscape mode. At that point, you can tape the template on the SF airbox and proceed to trim along the designated sections. |
If using a Cobb air box, print out the PDF attached below and use the template to cut the air box to allow the upper hot side pipe to pass though. The template should lay on the box like the picture below. the top of the template (once cut from the sheet) should be 3/4" from the top of the corner (blue arrow) of the box. Once the outline of the template is traced onto the air box, use an air saw or rotary tool to cut along the guideline to make room for the upper hot pipe. Once cut, cover the cut edge of the air box with the supplied edge trim.
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.
