why is it better than K&N, Stillen ect...

i searched but am still confused

looks?
sound?
gains?

 

The only possible reason anyone would say the Amsoil is better then the K&N is because the Amsoil is a dry filter and you do not need to worry about coating the MAF or the tedious and dirty reoiling regime every 10k to 15k miles.

As far as air flow and filtering efficiency, the Amsoil is not better.

As far as coating the MAF, just clean it when you change the filter which is something you should do any ways.

Read this for a quick lesson on air filters:

And to confuse you further, I would say my Streamline is better then both the Amsoil and the K&N

 

lol thanks for the info...


















but im still cofused lol

 

The advantage of poly or nano-fiber media is the ability to clean it periodically which you can not do with paper, along with not having to oil it to make it work to filter dirt effectively.

The only tests that appear to do a good job at separating the ones that actually filter out more dirt are these two:

Unfortunately, they are not up to date, (esp. the first one) and the Amsoil filter they test is the old oiled foam type. But it's a good general comparison between different paper filters as well, and K&N, where both tests seem to be in agreement.

I am not saying these tests are 100% conclusive, and your driving habits, air quality in your area, and how often you service your filters are factors also.
As far as gains, if you are relying on an air-filter to give you an edge, it's kind of like trying to scratch an itch you can't find.

I am hesitant to condemn K&N simply because it allow more dirt. Because no one seems to know how much dirt is TOO much!
Not to say ANY dirt is good.
There is a very fine test done at Amsoil to an SAE standard. I did not ref it because I tend to be leary of tests done by manufacturers and not independent parties. But you can easily find it.

 

thanks

 

I think it would be prudent to stop as much dirt as possible. The Streamline can catch particles as small as 1 micron in diameter.

And a filter that can match the OEM efficiency (consistently on the flow bench) and decrease restriction by 20% is a good candidate for someone that wants to do a fairly easy and safe tweak.

 

I would like to see a bench test with all these newer filters. It would clear the air even more (sorry for the pun). And tested to a standard endorsed by SAE, etc.
Not only mfrs.' tests.

But as I said, "The advantage of poly or nano-fiber media is the ability to clean it periodically which you can not do with paper, along with not having to oil it to make it work to filter dirt effectively."

So regular maintenance is still the key, as it usually is. Beyond that, nothing is better than what you are comfortable using. And I've used most types over the years, and could never feel or see a big difference, and never had an engine fail due to wear. I never kept a car over 150,000 miles either and that was a Celica on Castrol GTX with a factory air filter back in the 80's. It never burned a drop of oil (that was noticeable) in all those miles.
And now things are even better, supposedly.

 

i have an amsoil filter for sale for $30 bucks
