On my Diablo, I need to put mesh on each rear radiator, rocker intakes, quarter panel air intakes, engine compartment vents, muffler compartment vent, and engine air intake. I don't know if I will need any on the front of the car yet. It's hard to locate exact oem metal mesh but I do like the hexagon mesh so will probably go with that. Whether Diablo or Murcie, you will have to watch the air flow to your radiators regardless. If you are going with a 57% air flow and compensating with a higher cfm fan, you might end up in a pinch. We all want our builds to be Kool and Cool.
