Remove rear grill louvers for better cooling?

Has anyone removed the rear grill louvers or covers in the engine bay to aid with engine bay temps? It seems as though they block airflow out of the engine bay through the rear grill and removing them seems like they would help with engine bay temps. Thanks!

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

 

Note that my post above is not my car

 

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

 

I took mine off a year ago on my f430 with the challenge grill. Does appear to be for reflection prevention. When I drive over white road arrows/markings I get a pretty good reflection off the back glass. Startled me at first, but now is expected. I haven’t noticed any issues as of yet and would assume that the heat now has an easier time exiting the back of the car.

 

I removed mine for better cooling.
I wrapped the latch cable and wire in some heat insulation.

I wonder why the Scud doesn't have the reflection problem. Kdedrick said the Scud doesn't have them.

 

Maybe the plexiglass is less reflective? I’m not sure…
