I agree. The vent openings are way to small for a air combustion supply. Although with the AAR Fiberglass hood,we could have requested the opening be made larger for CAI with a water trap air box. Some want the vents for a cold air supply while some want them for just removing under hood heat. Jaguar XKR uses them for removing under hood heat only. There positioned so rain water drips straight thru and misses the engine. When we install them in our factory hood,something in our cramped up engine compartment is gonna get wet. I just perfer the rain water not to drip onto a new set of Need Wings aluminum manifolds or anything electrical. The vents flanges do slightly drop down from the hood and snap in. If the Needs Wings manifolds are actually taller than stock,may have to choose another location so the vent snap-ins on the bottom want hit the manifolds when the hood is shut. By spring time,I'll definately be doing this mod with some type of water drainage. I look as our hoods being a simple but costly bolt on item that can be purchased later if wanted to change back to factory stock. Don
