e-450 air intake mods ideas...

As the title suggests, I'm looking for ideas and opinions on mods for the air intake system for e-450s, specifically ones with the 7.3L powerstroke.

I've posted about the problem before, but to recap: the plastic cap for my assembly broke in the back. I have to replace it before using the bus again, and I'm getting very antsy.

The part I need is about $5 worth of plastic...

But the ONLY places that seem to have it will only sell the whole assembly, and the final cost would be ~$600!!!

I've called every salvage yard I can find a number for and scoured the internet. Nothing.

There isn't a lot of room to work with inside, but I do have the space originally designed for a battery (both are along the side on ours). Here are my ideas:

1. Get a 6637 filter kit from riffraff diesel and make it fit. Pros: $87, easy Cons: Drawing air from engine compartment, therefore starting warmer

2. Do some sort of mod involving a hood scoop. Pros: cooler air Cons: Unknown final expense

3. Do some sort of mod with a snorkel Pros: ??? Cons: ???

We're really stuck on this one.

An aftermarket filter. You could scavenge an intake tube off another vehicle and route it to someplace it could breathe. Even if it turned out to be a snorkel. I have seen some Jeep's run 3" pvc as a snorkel. You wouldn't need it to reach too high, just above the hood line.

Right. The snorkel would literally just be to get fresh air, not to avoid water, which is usually the point of them.

Is there anything more to a snorkel than a pipe coming from outside the compartment to an air filter then connected from there like usual?

Found a 99 e450 for sale for 1500 a couple hours away. claims the engine and tranny are good, but the turbo needs replaced and the top corner is crushed. I'd buy this before paying $600 for a piece of plastic.

I agree that is still way to much. seems $45 would be reasonable.
Are you able to put large hose clamps around the both halves and keep it clamped together. If you need something in a hurry you are going to pay.

Thanks, that's getting more palatable.

I fell down a rabbit hole of phone calls and found a place "in the boonies" of Ohio that has one for $5... but there is a crack! No gaps or holes though. So the current options are:

1. Pay $5 for a cracked one for temporary use until I find somebody parting out an e450. Seal the crack.

2. Pay ~$375 after shipping for the one mentioned above.

3. Do a mod and cut through one of the fenders and build a custom air intake.

Decisions, decisions...

basically its all just plastic pipes to get the air filtered and into the turbo.. since theres no Pics I cant get an idea.. however I do know a guy that used yard blower attachment piping to fashion up some for a car he was doing.. it was like 4 inch plastic pipe and was sold in various lengths..

is it the box itself that cracked?

Christopher, it's nor just a crack. There's a chunk missing that leaves a half inch gap above the filters.
