I noticed a way better and smoother pick up right off the bat. I have 't had it on long enough to notice any gas mileage improvements but it sounds sexy!!! Sorry the pictures suck. They were taken with a cell phone.

We've all seen the outrageous priced aftermarket air intakes out there. I still making payments so I needed something way cheaper. Everything except for the filter was purchased a Home Depot. The total was about $55 - $60 buck. $40 of which was spent on the filter alone. The filter is from Auto Zone or your neighbor hood car parts store. I bought a Spectre Performance reusable filter. I is 9 1/2 inches long and is adaptable to 3" 3 1/2" and 4" piping. I figured If I was going to make my own that I would make it the size I wanted. So I went with 3" piping.
Everything else was bought from Home Depot. 1 nylon barb to mip adapter (which is the white thing in pics below.) I found it near the sprinkler section. It's 1/2" x 3/8."

Next I bought a 2" to 3" rubber reducer from the plumbing isle. I didn't get a pic of it but I had to carve out a thin layer of rubber to fit it over the intake.

Next you'll need a 7 1/2 inch piece of 3" pipe and a elbow. There is about 4 different types of bends and curves. I bought all of them to see which one would fit best at home. Well none of them were a perfect fit but I did get close. Now I'm not sure which one it is by name but the model number on top is 5806-2. I think it's the one with the least curve in it. Also notice in the picture the left side is female and the right is male.

Connect the 7 1/2 pipe and elbow and test fit for you vac hole. I used a 5/8 wood bit and it was perfect to make the hole. Then screw in the white nylon barb.

Then carfully drill a hole to accept the sensor in the portion of rubber where it changes from 2 -3." Try to do it in the same spot as the picture so the pipe will fit in good. I shopped vaced the debrie out just in case. Then push the sensor in for a perfect seal.


Oh yea that filter was kinda leaning toward the radiator and was a little loose. So I made real quick strap to hold it in place.
the second pic is hard to see but it works great!!

I'm sure you see where I am going with all this. Finish it up, get all your tools out of the way, finish that beer and take that bit** for a test drive.

Hit me up if you have any questions.

nice work. but I don't know the thermal characteristics of ABS plastic, but I know first hand that PVC will shrink and melt in an engine bay. granted that the Jeep's bay is roomy and will not (should not) ever see temps over 180f, so it should be fine. The install looks great and clean, and an exelent way to use those McGyver skills Jeep owners are known for. just watch out for deep water and keep an eye on the adapter rings that the filter came with. they are known to 'loosen up' and cause the filter to fall off (personal experence). you might want to get another 3" to 4" bell adapter and maybe sand it down a little to get the filter to fit on it with out the rings. trust me on this one, you do not want the filter falling off and have no filter for the intake.

 

Thanks for the heads up bro. I did a similar install a few years back and it worked well for years. But it was a little civic. Thanks for the great tips I will use them. Oh I was thinking about painting it with several coats of heat resistant paint. Do you think that would help? Then to top it off I just seeing a intake pipe the same shape online for $40 bucks. lol

 

Real classy work here.



Seriously though, be careful going through wet streets.

Here is what I did with mine. I replaced the "accordion" intake hose with an aluminum intake pipe. Very smooth radius bend. I retained the stock air box uncut and unmodified, so there's less chance of hydrolocking than an exposed filter element.

 

Interesting. What kind of filter do you have? Did you get a good power gain with that? I got a really good high rev gain. Especially in second gear!

LOL I know I know. I was in a hurry to get accross town. I'm looking to make something stronger. Actually what I really need next is a shroud to cover it all. I was thinking about cutting up the OEM intake box like I seen on another post out here. I will diffidently stay away from water. But I live in AZ. It gets hot as hell but I hardly ever rains.

 

Thats great would you happen to have any pics of how it looks?

 

That's great would you happen to have any pics of how it looks?

You cant just search for everything on here, yes the trash can heatshield is searchable, but the roof vent boot isnt...
