are these a good idea? i want one to save my engine compartment from the heat. i'm told they are good to keep the turbo spinning easier.
i'm wondering if it also takes longer to cool the car after running (higher setting needed on turbo timer?).

anyone know?
thanks

 

does anyone know?

 

it might keep the engine bay cooler, but the compressor will probably heat up and cause the charge temp. to be hotter
