Cheap And Easy Intake Mod(Write up+Pictures)

Hey everybody Tj here from nisky. So as you might know the weather is pretty rough outside. I figured I keep myself occupied and help the cause by doing a write up.
I have seen a lot of good write ups to help other people and I figured I might as well do one. As easy as it may be. But here it goes anyway.

Things you will need:
Stock Yj’s (or any jeep for the matter) air box
Mesh (optional)
Regular head screw driver
Screws (small)
Wire cutters
Pliers (needle nose)
And about 20mins of your time.

What we will end up doing in this mod will be removing the air condenser and a plate that restricts the amount of air coming into the engine.
DISCLAIMER:yes this can be harmful if you decide to cross a river it can suck water into your intake, but other wise you should be ok.

First you will need to locate and remove your stock air box. It’s a lot easier to do the work inside.


Once you have removed it bring it inside and basically pull it apart with the tabs (as if you were changing the air filter).


Then you need to locate the condenser, it is the hourglass shaped hole in the front of the air box.


The easiest way to remove it is to push in the tabs with a screwdriver and pull it out.


Once removed this is what the condenser should look like. If what you pulled out if something different…you might want to put it back…


The next part is removing the plate that is on the side of the Stock Yj’s air box. Use the screw driver to pry the plate off. Try to keep it in one piece.


Then you want to cut out a piece of mesh that is the same size as the plate. The reason for this is to just keep any LARGE debris from getting into your air box.


Then just screw the mesh into the existing holes and you are all done with the mod. Just install it and listen to your engine purr because you just gave it new barks that will surly follow its bite.



Enjoy!







tell me what y'all think of my frist write up

The trick has been around awhile, however it makes it easier to suck water into the stock airbox (no more so then an aftermarket intake though). Just a warning to anyone doing this

Hi. I am wondering what people think of this as well. I am contemplating trying it. Seems like a great idea and cheap. That with new plugs, and throttle body cleaner, I would think would improve your performance. I have a 1992 YJ 4cyl.

Looks like you live in NY, so you have rough winters. I live in Illinois and have rough winters so was wondering about what the other poster was saying about water getting in. Is that a big issue? Its something I'm really looking at doing. Not being a wrencher, but a lover of interesting ideas, and a newbie, this is a project I think I could do and build some confidence, but don't want to hurt the jeep in the long run. Everything is stock on my jeep right now.

I took out the air condenser you were talking about, as well as another restricter piece in the top of the filter box. I thought about doing the Hummer intake mod. In this, you block the front intake, make a hole in the back of the filter box, run a tube/hose into the firewall and up through the top of the cowling just ahead of the windshield. This way, you get around the water issue, as well as getting a cold air intake out of it. Someone did a writeup on it, just search "Hummer intake mod", and it should come up. Great write up!

you shouldn't hurt it really at all. even if its raining like POORING you still wont get much water under your hood to begin with let alone up near your air box. what he is talking about is like, you deciding to drive thorugh a 3ft puddle...kinda...haha

My jeep is a DD, with a little bit of fun in the snow, but nothing crazy. Most of my Jeep is stock, so sounds like this mod would be ok for me. Thanks for the info

Funny reply fratis to the puddle comment.

Thanks

I have no tube from the front of the air box to the grill. Just a hole in the front of the air box like the pic I quoted has.. Shoot, maybe they are supposed to be that way, but it looks like something is supposed to be there.

I'm glad you guys like it. Would you believe nobody has ever asked me about it? I was expecting quite a bit of "what's that thing?" reactions, but no one has said anything at all.

I have a short plastic tube that goes from the airbox to behind the drivers side headlight. Sort of like having a cold air intake. Note I said "sort of like".
