Or maybe a cutting torch would be a good idea too. After the radiator is either protected or removed, of course. I had a thought about this, seeing as how I was thinking of trying that too. What if you live in a region such as I where it rains...ALOT? Is there any sock or material that anybody could suggest for keeping water out and still letting plenty of air in? Is it even necessary?
Just a lil food for thought and curiosity.

The air inlets are a few inches below the air box so water will naturally just run out. Should any water make it's way into the air box, the air box is fiberglass so it won't rust and the element will keep the water out of the carb. It's really no different than the cold air intakes that newer cars and trucks have, just bigger pipes.

I don't think that the rain will be a big issue.
I just wouldn't try going through any streams or deeply flooded roads.
One thing to consider is to use some sort of screen across the opening. That should help keep some of the bigger bugs out of your air filter. Not to mention that it will keep small critters (mice, kittens, birds) out of your duct work.

HAHA, I don't think I'll be fording any streams anytime too soon, and when I get this thing done, I'm gonna put it in high enough that puddle splash won't get it. I have started to amass my parts for this project, and before I saw that ramairbox site, I was going to try and plumb it in with stuff from my work, Home Depot. Just a suggestion for the snorkel at the front grill, in the pipe aisle at HD, they have deals sort of like funnels that are meant to bolt down to the floor in bathrooms of travel trailers or something. has the screw holes already in it, all you have to do is cut your hole in the radiator support, maybe use a little bit of silicone to help hold it there, and drill your bolt holes in the support. Food for thought, and my plan. I'll post some pictures one of these days.

For your snorkles there's an even cheaper option at Home Depot that will work better with the ducting. You'll find some 4" aluminum brackets made for the job. They have bendable "ears" all around. The problem is the radiator support isn't completely flat so the rigid snorkles, like the drain fittings you described, won't work too well. I'm also not sure that the PVC fittings are the right size for the aluminum ducting. What I did was drill a hole in each of the ears, then marked and drilled a matching hole in the radiator panel. I used a pop rivet in each hole, then painted the whole thing black. Looks good and will never come loose.

Good stuff, I was going to try to make the PVC fitting work because it seems that the PVC would conduct heat less. Oh well...I guess I have to put it all back together before I get too ahead of myself with ram air.
