I hear you and what you say makes sense, BUT every car manufactured now has the hood liners...check any bmw, porsche or even new alfa. So why do all the new ones have it if they are so bad?Think about it:
Anything that insulates or lines the hood is going to keep heat in the engine bay.
The only way to actually get rid of heat under there is to punch louvers in it, or get creative with scoops so that air is recirculated under there, not insulate it with something.
The whole psychological ploy with hood liners making things 'cooler' is that the hood feels colder to the touch from the outside when they're in use. (guess where the extra heat you aren't feeling goes, knowing that hot air rises above cold air?)
I bought one a while back but have decided not to install it as I just want to keep my 87 Quad as simple and original as possible. I have the original spec labels on the inside of the hood. I also want to be able to hear every sound my car makes, the good the bad and the truly wondrful sound of a well tuned Alfa powering through a twisting New England road. This product may fall into the category of "a solution looking for a need".
Because todays 'civilized' society wouldn't tolerate a new car that made a lot of engine mechanical noise. ('quiet' = 'quality' in a lot of peoples minds. Would you pay $100k for a car that had a noisy engine?
