    Be careful that they do not protect bumper from melting from heat from mufflers or wires etc .. every part has be designed with something in mind

    That piece is designed to be there, either to protect something like @flash32 said, to direct air to or away from something, or for some other reason. They are a very specific shape in a specific area. I would leave them.

    I had read somewhere someone saying they were there to prevent headlight glare from cars behind you at night. If that is their purpose I’d be tempted to remove them. There aren’t any wires or anything else that they are shielding heat from. I am hoping someone knows the true purpose of these as I haven’t been able to get a definitive answer

    Got my answer, on the 430 Ferrari parts diagram they are labeled left and right “Rear grill reflection deflector” so they are indeed there to prevent headlight reflection from behind and not as a heat shield.

    Interesting fact: the 430 Scuderia did not come with those deflectors, but F430s with the rear challenge grill still had them installed.

    I took mine off maybe 3 years ago. It's better for the heat to escape thru the rear carbon grill. I also added these 16m grills for the engine lid along with naca ducts in the undertray to scoop up air as i go down the road. Ive now have maximum air flow in and out of the engine bay

    Would you mind measuring the rhomboid shaped opening of the grille for me?
