Just for info the larger center grill comes out easily also. I must remove it to clean/oil the air filter on the cold air intake. It has some tabs on the bottom were it meets the bumper cover, and you unscrew the screws you see on the top of the grill when you have the hood open. It will lift easily out. I unscrew those screws on the top and reach down behind the grill from the top to release the tabs which hold it to the bumper cover.
