I have been reading and reading and reading MANY different topics on this subject on wrangler forum and jeep forum. From what I gather most people think they do nothing and can potentially do harm(don't filter as well, oil on MAS). A few think they work. On 4bangerjp I am noticing a lot more people are using them.
Please vote and let me know how much/little it helped or how you wouldn't make that mistake again etc...

I say no, its not worth it. Save your money for gas, you'll probably need it.

I did this: http://4bangerjp.com/forums/index.php/topic,3595.0.html (http://4bangerjp.com/forums/index.php/topic,3595.0.html) and then I installed this: http://www.rockauto.com/catalog/moreinfo.php?pk=489362 (http://www.rockauto.com/catalog/moreinfo.php?pk=489362) and I bet it is just as good as a CAI. My vote is no. The air hogs are $4.15 clearance at Rockauto.
-
It's all relative. The only engine mod on my YJ is the removal of the venturi/air flow restrictor in the intake. I don't really feel any need for more power.
-
Put this out there, instead of a CAI how aboutr a snorkle. Heard it mentioned here several times it would seem to kill two birds with one intake. Cold air and fording.
I've got a so called cold air intake, its kind of a pain took a while to get the whine out of it. And its not really a cold air intake a tube with a filter on the end, that draws its air from the engine bay.

PS Air cleaner has been changed its at least twice the size of the one in the Photo.

i assume by MAS you meant MAF, and yes in that case the oil can harm it but the Jeep uses a MAP and that's not the case, it can live with oil in the intake (lots of 2.5s have oil in the airbox from the PCV)

I don't know. I thought it was called the "mass airflow sensor". I do not know much about jeeps, I've only owned one for a month.
Thanks for the info although as of now I still have no plans for under the hood mods. I started this poll to get real life feedback on these things because it's definetly a hot debate on other forums but most that are calling them rubbish don't even have them.

yep, MAF sensor = Mass Air-Flow Sensor
-
the poll is not entirely accurate, like it's been said before by grumpygy his CAI (Cold Air Intake) is more a hot air intake. if you have a true CAI (enclosed and tubed to outside of the engine bay, or properly screened if not enclosed) then it will improve, otherwise a K&N or Airhog filter for your stock airbox is probably cheaper and as effective.
-
I say it's only worth it if you do it right. Otherwise, spend your money on something else.

My plan, if the YJ ever becomes a third vehicle, is to reduce the weight. Plans include:
1) Sell hard top and get a safari top
2) Sell hard doors and get soft doors
3) Remove rear seat and seat belts
4) Remove the carpet
5) Get plastic front fenders
6) Get synthetic winch rope
7) Reduce the width of the front bumper
8. Trim the rear bumper and make large holes in it all over
9) Make holes in the gas tank skid plate in all places that don't actually protect the gas tank
10) Get lighter suspension seats
11) Comp cut the rear fenders
12) Delete rear door, replace with just a single layer of sheet metal welded on and some cross bars to mount the spare
The goal is to reduce the weight by about 500 pounds. That should provide some improved acceleration!

As long as you don't go over 45mph. At speed, weight is less of an issue.

confused :puzzled: please explain
what happens above 45?

aerodynamic effects become a bigger factor and ditching the hardtop for no top or even a soft top increases the aerodynamic drag considerably.
-
Think it has to do with Aerodynamic vs the weight. Over 45 Mph Aerodynamics has more of an affect on your driving.
-
I had thought about a CAI also when I bought my jeep, but after removing the restrictors and hi-flow filter, I don't see a need. However when I get some free time again I might look into opening up the front of the airbox a little and fabbing a tube to behind the grill.

thank you

Actually, it starts at 35MPH but you won't really start noticing it till around 45-50mph. Keep in mind wind resistance goes up exponentially to speed.

I'm on my 4th intake setup over about 12 years owning my 4banger -- stock, open tube/filter, totally closed setup using Apollo-type filter and 3" tubing through the grill, and this Airraid kit http://www.quadratec.com/products/17008_104_07.htm that I got for a bit less than it's going for at Q-tec. It has the no-oil filter.
Jp magazine might have a point about jeeps -- typically they're referring to 4.0L -- performing better depending on the air tube and not so much the air filter -- http://www.jpmagazine.com/techarticles/engine/154_0804_jeep_wrangler_intake_shootout/viewall.html.
I read their test a few times and noticed Airraid was the only manufacturer using a tube that sized up from about 2.5" at the thottle-body up to 4-5" at the box. Airraid got the best torque numbers in the test, but we're not talking big differences vs. the others.
I've used an open filter on a tube kit and noticed the high end was better than stock, but the 4banger did seem to lose some low end torque. The Airraid kit seems to have the low end also -- this may have more to do with the air tube design than any "cold air" ingestion, though.
