I just finished installing both of these on my '06. Only modification necessary was to slightly enlarge the holes on the MPC. Of course I used slightly larger stainless screws that I already had. I opted for the black MPC because it looks factory. Ordered from Geno's, of course. Overall I am really pleased. The Kilby piece is really all that is necessary to protect the condensor. It covers the condensor completely, except for the back half-inch or so of the top side of the condensor.
