    Removing them just means you have the inconvenience of reflected light and glare.

    I tried it with them removed. Put them back straight away !

    This description must be wrong then "The two louvres that help evacuate the hot air from the engine bay need to be removed"

    not sure why my 430 Spider has a set then as headlight glare not an issue but sure it helps on a Coupe, I remember reading once that they were to reduce the temperature of the rear grill as EU regs state that no part of the external bodywork can be above a certain temperature. My engine bay is much cooler without them as they simply restrict the hot air exit flow. My SCUD never had them but then the rear grill is carbon and so doesnt heat up as much

    and there is very little driven airflow into the F430/Spider engine bay to push it out any other way

    The 348 has similar 'heat shields' around the exhaust and I know of a guy who managed to melt his rear light fixings having removed them. That could have been in conjunction with an aftermarket exhaust though, not sure, but aftermarket exhausts tend to be further from the bodywork rather than closer in a 348. I guess my point is I'm sure they're there for a reason, unless you have to, why remove them?

    Air isn't always driven out, it can be sucked out due to differing air pressures. Just a thought.

    Indeed...

    The rear diffuser is very aggressive on the F430.
    Worth following one on track in the wet to see just how aggressive it is and what that draws out of a challenge rear grilled engine bay.

    definitely going to wrap my cats, as they get extremely hot, even just driving the car out of the garage !
