I deployed a hybrid of the above techniques. I really didn't feel right continually to try to jerk them out so I removed the four torx screws on top of the bumper cover. Then pulled the bumper towards me bending it just enough so I could see the top retaining clips (thanks for that 411) . I then used a flat head screw driver to depress and push back the retaining clips and pulled the top half out, just enough to give me the leverage to literally rip the rest of it out. The retaining side is metal and will not be damaged. The original grilles are useless after.
