I'm adding an aftermarket intake to my 04' 5.4 & noticed on the bottom of my intake there was maybe 10 small drilled holes, ((1/8") in diameter. Are these holes OEM from the factory, & what is their purpose? Seems to me that the holes would suck in "some" hot air from the engine bay, yet it's main sourse of air is from the inside of the driver's side inner fender well. Any help with your knowledge would be appreciated.

 

Probably for moisture build up
