Basically, it's a pain in the ass. From the driver's side end tank on the IC, a pipe wraps around and up to a stock rubber coupler, then attaches to a stock plastic hard pipe and then to the hose to the throttle body. You'll have to move the metal tubing for the AC up a little bit so that the Apex hard pipe extends as far up as it can go. Good luck. BTW, I upgraded the stock soft IC hoses on the passenger side with the upgrade kit from the HKS Type-s IC and bought a 3 inch diameter 90 degree bend aluminum pipe, 3" silicon hose coupler, and 3" to 2.5" transition hose to finish off the soft piping to the throttle body.
