Cold Air Intake

[007]

Anyone running a cold air intake on their CJ? I'm considering one, pretty much piecing one together with Spectre parts. Not sure what my options are on where to get air from though.

Just curious, would like to see/hear of some ideas/solutions...

A cold air intake is the best way to go, I believe anyway. I would suggest a dual snorkel type. Which would probably require a lot of junkyard searching.

For my gm fi, I was planning to go with the chevy air cleaner housing with air duct hose going to the grill in the stock location. Maybe call to edlebrock and they could suggest a housing that works with their fi setup if your interested in that route.

Well the air hat and ducting and filters and so forth are the easy part... Just not sure where to get the air from. IS there a stock location?

 

[Posi]

Yes, passenger side of the grill, high and next to the radiator.

Okay. Well that's fine with me. I'll look for it tonight.

Thanks I'm not near a computer.

Jeep came stock with a cold air intake. Both my '84 with a AMC 258 i6 / 4.2l and my '78 with a AMC 304 have it.

Are you thinking of making something like this?

The part on top of the carb came off a mid '90s Cadillac 4.9L V8, it's a $15 amazon silicon adapter and an autozone $30 pipe that I painted black and plugged all of the excess holes, and an AEM dryflow airfilter.

How is that a cold air intake when it is drawing hot air from the engine compartment?

My 77 did not, it has the older / round-horn end on the air cleaner assembly. I do have the holes like Posi showed, but I have headlight wires coming out of them from my headlight harness upgrade.

My other beef is that any air from those places will be heated by the radiator at lower speeds, although cooler than compartment air nonetheless.

I'd like to find something to get really fresh air without a snorkel. I thought about pulling from the front wheel well, but you can get a lot of dust there so that won't work. I've also considered steeling the cowl vent and using that.

Here's a couple of write-ups for a guy that used a HMMWV mushroom intake on his TJ, you could make something like this work.

I've thought about routing mine through the firewall and into the cab to make sure out stays away from water too. I have a long way to go before I get to that point though.

You could drill a hole and use a grommet next to the stock cold air intake to send the wires through.

I like the mushroom intake and have read that article in the past that Elwood posted. However, it wouldn't work for me because I wheel with my windshield down and the mushroom intake doesn't allow for it.

If you don't mind not having the option to drop the windshield go that route.

Well I really, really appreciate the feedback and ideas and examples. I do like the Humvee idea. It's very similar to what you would find many tractors. The downside is that I don't know how much room I have under the cowl or where available space is, which I kinda why I'm back to thinking that coming in from the firewall side of the cowl vent seems like a good plan. There's already a water drain, and I could add a water drain to my intake tubing as well, before the inline air filter.

Could I just start cutting in the firewall in front of that cowl vent and just continue into it and plumb in a vent through there?

Yes, you would need to figure out how to get a filter in between, here's some more idea's I found, it looks like they're for TJ's, but same idea if you're resourceful.
