I'd say more of a fact than opinion. I vote for paper elements here.chimpboy wrote:My feeling is that conventional paper filters are the best.
IMHO the serious consensus is that K&N are gimmicky junk that flow a little bit more air but don't filter as much dust out of it.
But... you know what opinions are like

Stick with paper. unless you are modding the crap out of the engine & expect low life with maximum output dont bother.
When I had the injectors done the diesel bloke left the pre cleaner out of mine, I put it back in & didnt notice any drivieabilty change. I prefer engine longevity.
It is actually a proven fact that paper filters are better.
BTW, I replaced both filters on my MK with Unifilters, biggest waste of 300 bucks IMHO, no noticeable difference & it was a SD33T.
I just regularly clean my paper filters & get about 5 years out of them (obviously depending on use).

Its funny how everyone says use paper when in all the years I have been in the motor trade every car that has been in dusty areas has fine dust in the intake pipe after the filter!
Both my GU's run unifilters and never have had any dust in the intake pipe after losts of dusty trips. When you run the 2 stage filters i have never had any signs of dirt or dust on the inner filter but the out can by up to 5mm thick in build up.

I have never had dust past my k&n filters, I can only put this down to oiling then correctly.turbo gu wrote:Its funny how everyone says use paper when in all the years I have been in the motor trade every car that has been in dusty areas has fine dust in the intake pipe after the filter!

I only use K&N filters on performance street cars where you're after maximum airflow and to keep "rocks" out. I prefer paper filters in fourbies. I sometimes spray a sticky adhesive lubricant we have at work called Wurth HHS2000 on the flat metal top and bottom parts of the filter. I find it traps a hell of a lot of fine dirt that would otherwise be flying around the airbox or in the element. I think an oiled Uni Filter is very effective at catching dust, but my boss who used to maintain a fleet of Landcruisers used for geological mapping department out in the scrub, reckoned they clog up far too quickly in dusty conditions and are a pain to clean. With a paper filter its easy enough to give it a blow out in between services if necessary. Another thing I'm planning to do for outback trips is fit a precleaner bowl to the top of the snorkel.
read it again, said clean not gentle cycle and warm tumble dry. Use an air compressor from the inside. I have one in the truck that needs doing if you want to practice.nastytroll wrote:How do you wash your paper filter?chunks wrote:Yes but a paper a filter is alot quicker and easy to clean than washing and reoiling a Finer Filter.
Paper elements can be washed, there is a company near beenleigh that does it.
Blowing compressed air through a paper element perforates the filter, hence makes it less efficient then an oily peice of cotton.
I read "clean" not "blow".
I ran CNC's that use large barrel type aircleaner's for filtering die electric and de-ionised water. These were MAN truck filters. So why not was them?

no it just means the oiled filter gets a build up of dirt on the outside.grinch2 wrote:i would think that clogging up quickly would be a good sign as its cathing more dust. k&n make a foam precleaner that goes over the pods that they claim make them better and ive also heard that they do a few different grades one being for off road racing.
the paper filter traps the dirt IN the filter.
I've used the all, oiled foam, K&N and paper filters.
had the foam filter on my CRF450, Couldn't keep intake valves in the thing alive, the dust wears the crap out of titanium valves. it always had dusts after the filter. didn't mater if it was a new factory oiled filter or and old one i had been cleaning.
I used to use a K&N filter on a falcon i used to own. right from the start i noticed dust on the intake piping after the filter, but it was an old shitter and the filter was cheap so i left it there.
my patrol and the missus AU both use paper filters. they never get cleaned, if they are dirty enough to 'need' cleaning, they go in the bin and i spend $20 on new ones. neither of these two cars have dust problems
