Hello, this is my first post. We recently bought a 2017 Honda Fit to tow behind our RV. My husband removed the front bumper to put the base tow plate on, and the air deflector that sits behind the grille fell off. He didn’t know where it went and didn’t think it looked important, so he put the bumper back on without it. I’m wondering how important that piece is and do we need to remove the bumper to put it back on? I can’t find any information as to what exactly is the purpose of this part. Thanks for any help here! I’m attaching a pic of the part I’m talking about and a pic of where it goes. Thanks!
