K&N filters,your opinions?

[Land Yacht]

I personally think they are over rated, and I don't think they filter as well as paper elements. I could be totally wrong. I work on small engines as a hobby, the intakes on oiled foam filters are slightly dirty, those that use paper elements are spotless. K&N uses a cotton matterial rather than foam, but I still doubt they filter as well as paper. Many people swear by K&N, I'm just not one of them.

I've used them for some time, haven't had a problem so far, they seem to do a good job. Of course it's not  very dusty here either.

They spend a LOT on promotion,like Fram.

run a K&N or Airaid filter on a sand rail...

then run a paper filter and see the difference in the carb's throat inlet.

I've got over 125,000 miles on mine and the motor still seems good.  I've cleaned it twice and should do it again   .

That said I only have one on my truck.  If I ever rebuild the motor on the jeep, yes Tom I still have the motor you got for me, I'll put one on it also.  

It would have been cheaper for me to have put one on the jeep and my car years ago vs. keep buying the paper ones.  I just realized that  :cry:.

Of course this isn't a very scientific research project I've done, but there is more dust in the air here than back east but less BS .

I did a test a few years ago and now use K&N's on everything.  I had bought a 2000 GMC highrider small pickup.  It had about 7000 miles, so was almost new.  I carefully filled the tank and ran a 100 mile loop both city and hi-way driving.  Checked the mileage and changed in a new K&N.  Filled up and ran the same loop again.  This test netted a true 10% increase in mileage which was about 1.5 MPG on this truck.  I have been using these filters sense that test.  I also use Mobil 1 in all my vehicles and I'm a believer in that also.

i'm not a big fan of 'em.....
i probably see a lot more of 'em than normal people(cuz of what i do) and they have their problems...
mostly over oiling.
puts this nice coat of oil and fuzz on mass air flow sensors...
see 'em collapsed a lot too.

when the throttle butterflies stick from the grit with the paper filter, you have an answer and a hell-of-a ride too.

I agree Tom on the over oiling, but that is not the fault of the filter, but the person that installs it. I have had the same problem with MAF sensors, but if it's a fairly long intake pipe, it's generally not a problem.

[EMSjunkie]

I run a K&N  on my Coupe.

I agree with the over-oiling.

kinda dusty/dirty here, don't see alot of difference between
it and a regular paper filter.


I'll shut up now.
