The K&N was the best at what it claimed to be the best at. Free air flow.
One thing the study didn't talk about what how much tolernace for dirt did
the motor have? Were all air filters within the manufactures specs?
Less junk getting into your motor is a good thnig, but at some point it
won't matter due to your oil filter etc.
WHAT??!! K/N filters aren't worth the money??!! You mean their
literature is full of lies??!! What's this world coming to?
All kidding aside, I've never purchased a K/N filter for the simple
reason that, more airflow through a similar sized filter equals more
dirt. It's elementary.
I learned my lesson about creative marketing when I had a Aero Turbo
muffler installed on my truck. Their literature boasted large
increases in MPG with their muffler. I figured any increase would be
worth it. I didn't realize any increase at all.
That is why they call that stuff "after market." If ANY of the
stuff actually did what they claimed it would not be "after
market," because every automotive manufacture would be using the
stuff. Every manufacture is looking for every advantage over the
other to meet or exceed CAFE
Finally some are seeing the light! I've been preachin' against these
filters for years only to be villified for not knowing what I was
talking about. It's old technology that was abandoned by every major
engine manufacturer back in the fifties. I wonder how many folks had to
do a ring job on their engines due to these filters.....
Goes to show how gullible folks are when it comes to advertising. Ya
know, folks are still buying that Tornado gizmo that installs on a carb!
That piece of garbage was in the JCWhitney cat for $9.95 back in the
50s....same piece of junk costs $70 today. Oh well, if it seems too
good to be true......it is!
Most "after market" stuff does work. But then most after market is geared
at power and performance, which does not go hand and hand with CAFE, but
usually against it. The after market has been providing roller lifters and
rocker arms since the early 70's. why? Because they reduce friction in the
valve train, which frees up horse power, and allows higher rpms. Guess what
many auto manufactures are using these days? Do you think Chevy would have
put V-8s in the Monza if there hadn't been so many people using after market
to put them in Vegas? Or ford have put V-8s in the Mustang II if so many
people hadn't used after market kits to do the same with Pintos and Mustang
II's? Hot Rodders where rigging up snorkels with dryer hose and then after
market kits to get cool air from out side the engine bay into the intake way
back in the early 60's. How many manufactures don't have ducting from the
radiator horn to the intake these days? We knew back in the early 70's that
an air dam across the front made the car handle better, and run faster, that
ground affects kits got us better fuel mileage and handling.. How many cars
today don't have some sort of air dam and ground affects ether as an added
on piece like the S-10s, or incorporated into the bumper design and rocker
panels like the Mustang, Monte Carlo, Impala and the Corvette? The after
market has been providing performance suspension components for ever. Its
only been in the last 10-15 years that you have seen manufactures start
using teflon and polyurethane bushings, and performance shocks/struts like
Bilstien. It was the automotive enthusiast and the after market that got
sway bars on oem.
Like any other industy there are snake oil salesmen out there. But they
make up a very small percentage of the industry.
Of course if you were one of those that was always trying to get a bit more
out of what the manufacturer sold you, you would know this. OEM never does
anyhting that costs more till they are forced to by consumer demand and lost
sales kick them in the gonads and getting their attention.

I don't think either Chev or Ford sold many V8 Monza's or Mustang II's
I think they decided to design cars to better handle a V8 after those
The manufacturers did it back in the 60's 70's & 80's. It usually got
pulled off the air horn by people "hot rodding" their engine's
You mean like the 1969 SuperBird, Charger Daytona & Ford Torino GT? I
think the manufacturers knew, used and installed these devices on the
cars where they wouldn't be ripped off. Keep in mind the environment
the cars from the 1960's & 70's were driving in. The plastics, roads,
fuel & tires have improved dramatically since then.
Back to my earlier comment. Try driving down a gravel road on a car
with poly urethane bushings for more than 5 years. IF you could stand
the noise & feedback you'd be back at the dealer getting the bushings
changed so often you'd think Fiat is the way to go.
OEM wants to make a sale, & Keep the money, then make another sale to
the same person. If you sell a product that won't hold up, isn't
suited to the environment or will cause other problems you will either
not be able to make another sale to the same person or you will have
people asking for their money back (or both).
GM Makes amazing direct injection Diesels in Europe, However the Fuel
in this continent is so polluted and the roads are so rough that they
refuse to import them (an example of reality getting in the way of a
A group of highly trained engineers working as a team for GM Ford etc,
are more likely to arrive at a more workable automotive solution to a
problem than the average K-Tel inventor.
GM experiments & tries new things (i.e. the experimental CVCC 350 they
tried years ago) however they won't sell such a product to your wife
if it will leave her stranded outside of Fargo on a cold winter day or
won't work within the constraints of the EPA or CAFE.
What are the particulars concerning your Aero Turbo installation. I
know the literature makes claims that defy the physical rules of the
universe, but I keep hearing stories that seem to support their claims.
What year and model vehicle did you put it on, did you follow their
requirements? And what was the actual outcome??

Just my $0.02...
I bought a K&N drop-in filter for my '95 Jimmy at around 70,000 miles. I
noticed absolutely no difference in performance.
I later bought a CAI kit at around 120K miles and still noticed very little
difference in performance. At around the same time I replaced the muffler
and cat with Flowmaster (and whatever the cat was) models. It was at that
time, I noticed a bit more OTL increase.
IOW, the filter did absoletly nothing by itself.
On my '98 Maxima, I took a different approach - I ensured that the $1.50
Autozone air filter was changed every 4K miles when I did an oil change.
Having just bought a Saturn VUE on Sunday, I plan to do the same.
This technique provides two advantages - first I don't let too much dirt
into the engine, where it "could" possibly cause some future damage.
Second, I ensure I always have a free-flowing filter at a very low price.
Anybody need some bottles of K&N filter oil?
