I bought the CZP setup you have pictured and was pleased with it. Then needed a single replacement intercooler and they wanted nearly what the pair would cost. So I bought an Asp Spec set from SZ (Like others here recommend, versus direct purchase). The Ash spec intercoolers fit even better due to the cast end tanks versus cut and welded ones on the Bell. I also installed Z1 Intercoolers and piping. Fitment was terrible in comparison IMO. As a note, the Z1 intercoolers were not designed to work with AshSpec Planar intake piping regarding fitment of the recirc valves from my experience. Had to cut and re weld Recirc attachment tubing on the Z1 intake pipes.
