Cold air intake vent

[zouch]

if what you're after is cooler intake air and don't want to go to a real snorkel, have you considered some of the aftermarket hoods that have a more direct flow for intake air?

i'm not promoting this one in particular, but they've posted some interesting images showing how much cooler the air is flowing the the Air Box with an intake on the leading edge of the hood. (pics are of a Gasser, but the concept would be the same for our Diesels.)

Maybe I am missing something, but there's not much of a gap on my hood. The way the airbox seals to the hood, I only see it as getting a very restricted air path, some of which may come from between the insulation pad and hood. Where this concern partly came from is the assumption that some comes from the cavity formed there. Now that I have opened the vents and the engine can exhaust some of its hot air through them, that cavity has engine-bay-temp air.

Thank you for linking that @zouch

We did a fairly extensive test showing the benefits our JL H.E.R.O. Hood in terms of reducing engine bay heat and getting cold air to the air box. The below pic is my favorite because it shows how effective the ram air truly is.

And yes, we do have a version of diesel owners.

I wish Rugged Ridge made this one for the Ecodiesel's so I wouldn't have to cut a hole in the hood.

I've been bugging them for a while on that, they won't budge. Especially since the 3.0 is discontinued.
