So they are used to prevent a high pressure build up under the hood.
Am I seeing some kind of fan assembly in the last couple images?
Thanks again.
Not planning to do an exact duplicate of these.
Just something small and tasteful in the same vein. I figure they can't hurt with respect to heat and under hood pressure.
And, it would appear from this image on your p photo bucket that I'm not the first to think this might be a good idea.
