K&N Air Filters
 

I've been thinking about installing one of these in my 07 Santa Fe 3.3L.
Are they worth the extra cost? I've read that there is a noticeable
increase in performance, and maybe gas mileage. Any problem with the
Hyundai warranty?

This question comes up quite frequently in all auto newsgroups. DAGS and
you will find a lot of both opinion and experience on the matter of K&N. I
think you will find it sums in favor of staying with your vehicle's OEM type
filter. K&N gets the good in its reputation from the openness of the filter
media - and the bad in its reputation.

Yeah, there's two camps on this debate. One says the performance
increase is worth it. The increases airflow lets in more garbage so
you're either maintaining the filter more frequently or you're getting
more but dirtier air in your intake. Stick with the kind you've got,
it's cheaper over the long term.

If this would be an oiled filter, there's also speculation that the oil can
get on the air flow sensor and damage it. If you had an oiled filter on
the car and needed an air flow sensor, you might see the manufacturer
refuse warranty service. You may also have a potential problem with the
engine warranty, depending on the type of engine failure. A valve sealing
issue or cylinder abrasion issue may be able to be blamed on the filter.

I'm in the keep it factory camp myself.

Thanks for your expert advice. Now I know what to do - or, actually,
what not to do.

Ed,

If you have a fire breathing 400hp engine and push it hard, you may
notice a difference in power and gas mileage using a K&N. Anything you
would notice with a mild family SUV driving normally is probably
placebo effect.

Conversely, the stock filter on your Santa Fe would probably handle a
300hp engine with no measurable reduction in mileage or performance
until it gets very dirty.

The above is my humble opinion. I may be wrong, but I bet I'm very
close.

Re: K&N Air Filters
 

K&N filters work in racing, but consider that race engines have to
last a couple hundred miles at best, and then the air filter is thrown
away and the entire engine is usually torn down and rebuilt. Any
damage from the air filter not filtering is negated.

Compare to a typical family car, where the filter stays put for a year
or worse and is expected to last tens of thousands of miles.

The same can be said of other parts used for racing: oil, wires,
tires, etc. There are some things so specialized in what they do that
they simply don't belong on everyday cars, no matter how much the
advertising wants to tell you otherwise.

Yes, try racing slicks in a heavy rain... :-)

Depends on how long you keep the Santa Fe. If you keep it for the million
miles of the filter warranty it should be cheaper than the cost of all the
paper frlters you did not have to buy. AAMOF I think that the payoff would
come even before 1 million.

There is a slight bit of a performance improvement and no change in gas
mileage.

I have had K&N filters in my 2002 Elantra GT, 2005 Tiburon GT (which now
has a cold air intake), 1996 Dodge Grand Caravan 3.8l, and a K&N Typhoon
SRI in my 2003 Mitsubishi Lancer and all have had the results in the
previous paragraph.

I have followed the instructions for oiling my filters and found the
instructions sensible in that they appropriately caution against overdoing
it. If properly done there is no likelihood for oil to leave the filter
material and blow into the air stream in a naturally aspirated engine.
Personally, I have never seen evidence of oil or oily dust downstream from
the filter.

Just my experiences.

A lot of engineering has gone into the designing the stock filter that
comes with the vehicle. It works great, a compromise between
unrestricted airflow and filtering ability. I doubt a K&N filter will
give any noticeable difference in performance and it just may be
detrimental (MAF sensor etc..) If it's less restrictive, it filters less
efficiently. You save gas, your engine wears out quicker.

Save your money for some Amsoil (just kidding).

And yes, Hyundai could very well deny warranty coverage.

You got me! I was just about to jump in with both feet until I read
the "just kidding" part. :D

It never ceases to astonish me that very smart people fall for snake
oil.

I'm currently using Amsoil Transmission fluid and am much more satisfied
with it than the OEM.

What is different or what makes it "better" than the OEM? What do you
notice being different while cruising down the highway?
