I found this by accident the other while searching for an oil filter test. I'll pass on K&N and Amsoil I'll take an OEM.

so i take it your going to stick with your paper air filter element

 

Nice find Grateful, very interesting article, thanks for sharing.

 

I think everyone who's running a lower restriction filter probably realizes it lets through more dirt than paper filters. It's a trade off. I read some time ago in one of those muscle car mags that a street car with NO filter would go 30,000 miles before needing a rebuild.

 

ya that article shows that the filter doesnt trap much dirt, but look at its flow ratings, their the highest the whole time, with more flow comes less restriction, as stew said its a trade off. i run a cotton filter, and live on a dirt road, my angine has atleast 70k miles on it with an intake aand a cotton filter and everytime i clean my filter and feel inside the intake, theirs no dirt, not even a light layer of dust, at all. and my engine is still running strong. thats why we oil our filters, it increases the restriction, but it stops all that dirt ya know.

 

frequent air filter cleaning and oil changes will decrease and compensate for the dirt getting into the engine

 

One reason I passed on an aftermarket filter for my scion, its not like the stock filter is that restrictive in the first place or I drive it at WOT.

 

it only shows a 3% difference in cleaning effectivness between the K&N and AC Delco. WOW. Ill take the extra horsepower thank you.

"My motor is gonna last 3% longer than urs cause i use a paper filter" doesnt that sound just a little silly.

 

that's just me though, sorry if that sounds mean

 

Interesting find. Im still going w/ a k&n filter though

 

Very nice read, especially that we get to see the facts. Will it make me change from useing my k&n filters? Notta. I like what I use becuase I can wash it and make it as good as new. I have never seen a spec of anything in my intake tracks so I am confident in what I use....

But all in all, yes a very good read!

 

great read...still staying with Amsoil and k&N
