K&N on 2002 Sonata. Anyone tried this yet?

So what are the caveats on replacing the air intake with a K&N? I was
under the impression that you're not pulling as clean of air for the
sake of a couple of horses and "slightly" better gas mileage. Anyone?
Cheers.

K&N Air Filters do just as good of a job as the stock factory filters
that most manufacturers use (and a better job than most aftermarket
filters). There is no downside as long as you follow the directions
when cleaning it. I have been using K&N Filters in my last 3 vehicles
and have never had any problems.

DO NOT USE A K&N, Ford and GM are voiding warranties on vehicles that
are using them.
Both have issued notices about them. Also a few studies have shown that
the K&N let much more dirt and dust through than ANY paper element.

First, Inspect the vehicle for a reusable aftermarket oiled air
filter
DO NOT repair under warranty if concerns result from the use of a
reusable aftermarket oiled air filter.

The installation of an aftermarket reusable, oiled air filter may result
in:
a.. Service Engine Soon (SES) Light On
b.. Transmission shift concerns, slipping and damaged clutch(es) or
band(s)
c.. Engine driveability concerns, poor acceleration from a stop,
limited
engine RPM range
The oil that is used on these air filter elements may be transferred
onto
the Mass Air Flow (MAF) sensor causing contamination of the sensor. As a
result, the Grams per Second (GPS) signal from the MAF may be low and
any or
all of the concerns listed above may occur.

When servicing a vehicle with any of these concerns, be sure to check
for
the presence of an aftermarket reusable, excessively oiled air filter.
The
MAF, GPS reading should be compared to a like vehicle with a OEM air box
and
filter under the same driving conditions to verify the concern.

Transmission or engine driveability concerns that are the result of the
installation of an aftermarket reusable, excessively oiled air filter
are
not considered to be warrantable repair items.

Subj: K & N filters
John: If I wrote "subjective" I meant "objective".. I was responsible
for evaluating re-usable air filters for a major construction/mining
company that had hundreds of vehicles ranging from large earthmovers
to pick-up trucks and salesmen's cars. This study was embarked upon due
to the fact that we were spending upwards of $30,000 a MONTH on paper
air
filters. Using them one time then throwing them away.. I inititated
the study in that I was convinced that a K&N type filter or oiled foam
would save us many dollars per year in filter savings, man hour
savings, and of course engines as these would filter dirt better than
paper.
(yes, I had read the K&N ads and was a believer)

Representative test units were chosen to give us a broad spectrum from
cars right through large front end loaders. With each unit we had a
long history of oil analysis records so that changes would be
trackable. Unfortunately, for me, every single unit having alternative
re-usable
air cleaners showed an immediate large jump in silicon (dirt) levels
with corresponding major increases in wear metals. In one extreme
case, a unit with a primary and secondary air cleaner, the secondary
(small
paper element) clogged before even one day's test run could be
completed. This particular unit had a Cummins V-12 engine that had
paper/paper one one bank and K&N/paper on the other bank; two
completely independent induction systems. The conditions were EXACTLY
duplicated
for each bank yet the K&N allowed so much dirt to pass through that
the small filter became clogged before lunch. The same outcome occured
with oiled foams on this unit.

We discontinued the tests on the large pieces almost immediately but
continued with service trucks, formen's vehicles, and my own company
car. Analysis results continued showing markedly increased wear rates
for all the vehicles, mine included. Test concluded, switched back to
paper/glass and all vehicles showed reduction back to near original
levels of both wear metals and dirt. I continued with the K&N on my
company car out of stubborness and at 85,000 miles the Chevy 305 V-8
wheezed its last breath. The top end was sanded badly; bottom end was
just fine. End of test.

I must stress that EVERYONE involved in this test was hoping that
alternative filters would work as everyone was sick about pulling out
a perfectly good $85 air cleaner and throwing 4 of them away each week
per machine...

So, I strongly suggest that depending upon an individual's long term
plan for their vehicles they simply run an oil analysis at least once
to see that the K&N or whatever alternative air filter is indeed working
IN THAT APPLICATION... It depends on a person's priorities. If you want
performance then indeed the K&N is the way to go but at what cost???

And no, I do not work for a paper or glass air filter manufacturing
company nor do I have any affiliation with anything directly or
indirectly that could benefit George Morrison as a result..
