Check this out - Should I buy it?

http://cgi.ebay.com/ebaymotors/97-04... 230075773301

It looks cheap but by the time I'm done with US / CAD $ conversion and
$38 shipping I'm looking at $77. I don't see a long aluminum tube
usually associated with air intake systems. I'll hook it up to my stock
air tube? Thanks in advance.

I was looking at one of those too, but I haven't done anything about it
because I'm kind of turned off by the low price - seems too good to be
true. That one looks like you have to use the stock tube.
If you buy it let us know how it goes w/r/t quality of product, etc.

In my opinion those snake oil products only are good for one thing,
lining the seller's pockets....

On a normal fuel injected engine, adding a 'faster flow' filter only
means you are opening it up to dirt intake. Unless you do some serious
modifications where you can 'use' the bigger intake, it is detrimental
to the engine for nothing except a nicer sound maybe.

(remember flipping the air filter tops on 2 bbl to make them 'sound'
like a 4 bbl. We used to swear we had more power with the noise too.
LOL!)

As mentioned it also will fail emissions normally so you need to keep
your stock setup to put back on for the test.

Just my $0.02,

So true I only run it to 3000 RPM normally. but 10-15 hp increase at
peak RPM is what they advertise.

Mike: I truly don't think more flow means more dirt. I have always run
K&N oil filters and they are higher flowing and trap more dirt. If cone
filters let more dirt thru I don't know why they sell so well. Still
lost.

I asked Billy Ray the same question:

"So why do people keep
buying them if there really is no discernible gains?
Is this all conical filters or just K&N?
I'm amazed that the AC Delco paper filter allowed the least amount of
dirt and clogged up the least quickly of all those filters.
So...I might as well forget the intake upgrade and stick with the stock
box.
what else can I do as far as air flow is concerned? Throttle body
spacer? I've always kinda thought they were a little hooey, too, but
I don't know."

Billy Ray said this:

"Why? Hmmmmm
They spend millions in advertising a product that isn't totally useless
that promises significant improvements in horsepower and torque.
The problems include poor filtration and the power improvement is at
RPM ranges where Jeepers rarely venture.
Your factory filter and airbox is capable of flowing more air than your
engine can consume and exhaust.
On a stock engine spacers are also of little benefit.
You can get improvement from a free flowing exhaust. The best
bang-for-the-buck on almost any vehicle is a cat-back exhaust. The 4
liter engine breathes best through 2.5 inch pipes. In an older vehicle
or if you have some spare cash you can add a low resistance catalytic
converter.
If your exhaust manifold cracks you can replace it with superior one
but it is questionable if replacement is cost effective if your present
one is in good shape."


Hope this helps.

K&N 'themselves' admit they let in more dirt as the compromise for
better flow.

You should 'really' look at that link Billy Ray made. The test show
that K&N to let in 'way' more dirt than any stock paper filter....

You can't get something for free when it comes to power....

I guess, but I'm sure oil filters are a different ballgame.
Sigh. I'll stick with my stock box and get headers eventually.
Thx again

There is a really easy way to find out if a better intake can benefit
you.

You need a friend with a stop watch and you need a 50 mph road to be
safe for this test. Mark a start point and floor it from a stop to red
line in 1st, then hit second and when it hits 4500 rpm have the
passenger hit the stop watch and mark the speedometer. In my CJ7, that
would be 54 mph or so. 52 mph at 4400 rpm for sure.

Then take out your air filter and do it again.

See if a cleaner flow gives you a boost or not.

Sounds good - rethinking things I guess I need to get out of my
sportbike mentality. I have a 98 Honda CBR 600 and it screams to 13,000
rpm. Gains up in higher rpms are wanted. I put in a K&N air filter and
noticed the gains right away at the drag strip. My 1/4 mile time went
from 11.52 to 11.05 (constant reaction times of .2 to .3) I need to
adjust my mentality - WHY do I need more ponies? Climbing, tearing down
that stretch of open gravel road, tearing uphill with force. This can
all be done in a lower RPM especially with a 4.0 L. You just don't need
to be at 5000 rpm offroad. I'm not buying that filter.
