Here's a pic of my intercooler with the WWRS kit. The piping is run pretty clost to the core support and has 2-90 degree angles to go into the intercooler. PS cooler goes away on my car, i just put a hose in it's place. My intercooler has 1 bracket on top and 2 on botttom. The top bracket is in the center and bolts into the same hole as your horns. The 2 bottom brackets bolt to 2 existing holes on the bottom of your core support.
Not sure of the exact dims of my intercooler, sorry...
