A/C cooler protection (grid) for Renault Megane II (2005-2007)

I made this grid to protect my air condition cooler after I bought a new one. Inner side of bumper looks like someone missed add some part, but I wasn't found a car with anything fitted on this pins.

Grid was tested for one year (summer with AC) in my car (1.6 16V). Engine temperature was without change (from OBD too).
Engine and AC cooling through this grid looks sufficient.

But maybe manufacturer removed similar grid in first series from any reason. I believe the reason was to sell more
