First test fit the intercooler behind the grill. The bottom portion of the grill has to be removed in order to get the intercooler in there. Once thats been taken off, center the intercooler as best you can on a jack or have a buddy hold it in position. Put on you intercooler pipes and see how well it lines up to the intercooler. If they lline up good. Look at the top of the intercooler where the 2 mounting bolts go. Take your measurements and drill the 2 holes in the upper rad support for the mounting bolts to the intercooler. After you drill it, bolt the intercooler into position with the bolts. Then put back on your intercooler pipes, and thats what secures everything into place with no movement. After that, go get a nice cold beer and relax, your done.:tongue:
