FWIW Jeep Hi Pro Air Intake.

Just bought a hi performance air intake system for my '04 TJ six. I
figured I'd mention it because it's not K&N or one of those other
aftermarket add ons. Made for Jeep labeled MoPar. My dealer says it
won't affect my warranty! I keep track of my gas mileage so I'll be able
to spot any improvement (or decrease). The slight power increase claimed
is pretty subjective and I have no way to really test that. Got a "deal"
on the instalation. I had it done in conjunction with my 21K service. No
charge for the 21K service. Every little bit helps. :-)

Hmm, I put a Turbo City intake product, a cat-back exhaust system and some
other goodies on my four cylinder Wrangler some years ago. I definitely
noticed an increase in gas mileage, and now is a time to go for that, unless
you are rich. (

Did it seem to be a little "stronger" as well as increasing the mileage?

Too close to call. The cat-back helped me keep track of when my daughter
came home at night. The mileage increase was real and measurable. Maybe I
felt a little "seat of the pants" power increase, maybe not. With the four
cylinder, every horsepower helps. I wish I could tell you I was doing
wheelies...

FWIW the stock air plumbing is a well known to be less than ideal for
power, this is true of almost ALL fuel injected vehicles intakes. The
reason being they are required to meet NOISE regulations and fuel
injection is NOISY stuff. so they are plumbed with more bends then
needed to bounce the sound waves off of accoustically absorbant rubber,
they are longer than needed to get more of the above. They are made out
of less than ideal rubber tubing; which doesn't ressonate but which is
prone to being sucked together thus constricting the flow; Into an "air
box" which holds a filter but also provides a muffler like noise
canceler, and a muffler like space for back pressure, into (finally)
another bit of tubing often called a "snorkle" which is usually even
softer rubber.

This is why there's such a big industry around Cold Air induction, which
throws that crap out in favor of less bends, metal pipes, and big air
filters without a box or snorkle.

You called that right. I was looking at the parts taken off and lo and
behold snorkle, air box, etc. I don't detect any increased noise and a
hill that was a downshift from 5th to 4th is now 5th only. Mileage will
take a few more tanks to verify, but I know it didn't drop any. The
installation even looks good. Aluminum tube with a big blue "MoPar" on
it. Although "Jeep" would have been nice. :-)

Funny, everything you mention isn't present on a TJ. The intake parts are
hard plastic that doesn't deform under vacuum, with a bellows molded in the
intake tube to keep engine vibs from transmitting to the body-mounted
airbox. The TJ intake is just as long as it needs to be to reach the airbox,
which is located in pretty much the only place it could be under the hood.
The air box/intake trumpet is designed to acts as more a water-entry
protection than a big muffler.

There's such a big industry because it looks cooler under the hood. If it
really increased mileage/power, don't you think the OEM's would be all over
it?

I've no idea what you're on about... Is it your point that they don't
use softer material because you looked under the hood of your TJ and
found plastic instead of rubber?

Maybe you're trying to prove my point for me? The intake hose on older
4.0's is made out of rubber, I know, I've got one sitting in my drive
way. I'm sure they changed to harder plastic on your TJ because they
wanted to optimize the HP and fuel economy every bit they could within
the confines they have to work under (regulations and industry standards
etc).

> There's such a big industry because it looks cooler under the hood.

Hmmm I guess your point is that they don't work and are only for
looks... and that OEM's always optimize for power and never compromise
for noise <shrug> I'm not going to try and part you from whatever
notions who've got. There are a thousand dyno numbers, and auto industry
noise regulations, floating about on the net if you wish to educate
yourself. Your starting point should be inquiring as to why many
manufacturers call the rubber tubing before an "air box" a "SILENCER"
That should get you on the right track.

Great logic, so by your "reasoning" OEM's always produce and engineer
all their components for optimal performance... So would you say a stock
mustang GT comes with an optimal exhaust system, engineered with only
performance and fuel economy in mind?

Let's put it this way, would you trade me your plastic intake for the
soft floppy rubber one off my 92 XJ? If the softer one was adequate then
why did they change it?

Results on first tank: 254.4mi 10.950gal Wheels and tires 235/70x16 on
16x7 steel wheels. This is on an otherwise stock '04 Wrangler X.
Mostly (90%) on paved roads running the a/c about half the time. I can
live with it :-)
