Re: 2007 Tuscon Mileage
I don't recall the incident in which you refer to, however I do offer my
rebuttal:
http://www.knfilters.com/filter_facts.htm
It's ironic in the fact the AC Delco filter finished 1st in all categories,
when considering the test vehicle was a Chevrolet....although the claim is
made that the testing facility offered to perform all these tests for free?
The machine was $285,000....

I do not understand why people buy SUVs. They are
not economy cars. If you want gas milage, get a Prius.

Interesting how they make no comparison tests of their filter to other
filters. And how they use only "coarse" dirt in their testing.

The test wasn't performed by or commissioned by Chevrolet or Delco. It
was performed by an owner of a Chevy and an owner of a Ford. I've seen
other similar tests of K&N filters compared to OEM paper and the results
are always the same.
Like I said earlier, your car, your choice.

The incident was the failed rescue attempt of the Iran hostages. This
mission had many problems, but one was that the helicopters couldn't
handle the sand and dust...

Thanks for the opportunity to debate Matt. It's refreshing to hear one's
point of view.

A couple of points:
1- K&N lies, period. All you have to have is a basic understanding of
filtration and you'll realize that their claims are nonsense (I used to
be in the filtration industry). Except for a few out-and-out scam sites,
I've rarely seem more misleading or blatantly untrue information posted
on a website. Based on that, I won't trust them at all.
2- The military has their own specs for the products they buy and there
in not necessarily ANY correlation between products supplied to the
military and consumer products from the same company, ANY company.
3- Racing applications are essentially meaningless too, as racing
engines only have to survive for the length of a race, or at most
between frequent rebuilds. Their main concern is horsepower output, not
longevity. That's quite different from an engine that's expected to last
well over 100,000 miles without a rebuild in a typical car.
4- Every independent test of air filters I've seen has drawn the same
conclusion: K&N filters improve airflow at the cost of a loss of filtration.
As Matt said, it's your call.

Re: 2007 Tuscon Mileage
I echo southluke's response. Why cry about mileage when you buy an SUV?
Look around the roads and imagine how much less fuel we would use if the
SUV's of all sizes were off the road.

Re: 2007 Tuscon Mileage
The K&N filters do help airflow but beware of overoiling the filter when you
clean it. The oil vapors will destroy your mass airflow sensor. Also, It
really shouldn't impact fuel economy because the fuel/air mixture is set by
the computer. If air flows in more easily through your filter, the computer
will still adjust to the same mixture. The K&N's are great for older cars
before computers but do nothing for newer models, IMHO.

Re: 2007 Tuscon Mileage
Many of the Jeep's have absolutely horrible mileage. The Jeep Liberty was
really, really bad. My boss had one as a company car and was lucky to get
15 mpg.

Snow. Many SUVs are good in snow because of 4WD or AWD. Econo cars with tiny
tires are not.

Re: 2007 Tuscon Mileage
Back in the 'old days', I drove a VW beetle through some major snowstorms in
NE Pa and never got stuck, so the argument of large is better in snow isn't
always true. Driving in snow is more a function of the skills of the driver
and familiarity with his car's reaction in snow.

NE Pa and never got stuck, so the argument of large is better in snow isn't
always true. Driving in snow is more a function of the skills of the driver
and familiarity with his car's reaction in snow.

In theory, you may have a point, but we get a fair amount of snow here and I
see more SUV's in the ditch than plain old sedans. Could partly be the
superiority attitude of the SUV driver that thinks his high center of
gravity vehicle is invincible. 4WD is better in deep snow, but on a plowed
highway, good tires and good driving skills are the better choice.
Best car I ever had for snow was a Corvair with 13" wheels.

Fuel economy isn't just a function if air/fuel ratio. It is also a
function of pumping loss. Pulling air past a restriction requires
energy and the energy comes from the fuel. A less restrictive intake
and/or exhaust will reduce pumping loss and in theory will increase fuel
efficiency. However, the restriction from a paper element filter is
extremely low to start with so the K&N advantage is very small. I'd be
very surprised if the difference in fuel economy is enough to even
detect without very sophisticated instrumentation. A K&N may flow
better when heavily loaded than will a paper element filter, but very
few street vehicles will clog a paper filter in even 50,000 miles. I
still have the original air filter on my 2003 Dodge minivan at 85,000
miles and it is barely dirty. Unless you drive off-road or on a lot of
dirt roads behind other vehicles, you simply don't pick up much dust.
Old cars had the intake inside the engine compartment behind the front
wheels and the turbulence in the engine compartment from normal airflow
and the big old metal fans would stir a lot of road dust up around the
engine where the intake snorkle would pick it up. Virtually all modern
vehicles have the air intake up high behind the grill with a plastic
duct carrying the air to the air filter and then the fuel injector.
Even on a dirt road, you don't get dust into the top of the grill unless
you are driving behind another vehicle or passing a steady stream of
vehicles going the other direction. This is very different from the
"old days" when the engine compartment intake would pick up dust from
your own vehicle, not just other vehicles.

Re: 2007 Tuscon Mileage
Brian and Matt;
Thanks for the information. I will definitely reconsider their use based
upon input from you and others. I'm still garnering input from others and I
hadn't thought about the 3rd point Brian made.
In all reality, I don't do much "dirt" driving, and yes, the snorkels on
both vehicles are higher than normal.
Mileage vs. longevitiy? I plan on keeping this 06 Sonata post-100k.
