it would be a good idea to test the full intake system, along with the aps cold air intake and the arc intake box

 

If you want to send those to us for a test against the current setup, please do. If you want to do the test yourself, please do. If you want to post up ideas that are outside the scope of this test, even though we already said that it is just an air filter test over and over and over and over then please......ugh, nevermind.

 

Negative...

If you do not re-oil the foam, the Perrin filter is not going to filter well.

 

While i don't disagree i have seen no evidence on filtering quality for oiled vs unoiled.

 

There's enough oil remaining on it to filter. Thank you very much...

If the filtered worked well enough unoiled, then Perrin, K&N, etc, would not hassle with oiling their filters.

 

i guess it is all about your perception of "filters well enough".

I know many domestic guys that run the K&N unoiled as well.

 

 

Care to comment?

 

I do not suggest running an oiled air filter w/o oil for the sake of degraded filtering ability and increased dust/dirt/sand ingestion. Regarding the Perrin, it definitely comes soaked in oil so there is no harm in removing the excess like I did by blotting with a paper towel. I know CBRD actually sprays the filter down with some Simple Green and then rinses the filters before use. To me this is a bit excessive, but it seems to work well for him. If someone prefers to run a dry air filter, I suggest the Amsoil.

 

Need I? Running a K&N unoiled? Their filters are certainly not known for their dry performance. They're actually known for excellent performance when wet and somewhat dirty...

 

Not to start an argument here, but K&N air filters really aren't excellent at anything; they are on the low end of the power spectrum and their filtering abilities falls somewhere in the middle. I've run them on a lot of cars with no complaints, but now I just see too many better options.

 

No where on this thread was there a test of filtering ability. I'm not a K&N fan boy but it seems like a lot of folks have jumped to the conclusion that Perrin and Amsoil filter best. Most of the Amsoil claims come from the guy selling them, and even he has not actually published any data on filtering (no bashing intended). I personally am not making any claims as to filtering superiority but I just had to say something about this topic.

 

Exactly Correct !

Not only do they need to be oiled to filter at least half-assed, it is not just any oil and a filter oil must be used.

If the filter has been washed, there is not enough oil on it.

It is there engine that is getting sanded.

Saying many do it, certainly doesn't make it right. Many people jump off bridges, doesn't make it right and I for one am not going to follow them.

That is the perfect way to get the proper amount of oil on the filter. Any type of cleaning or using a chemical will dilute the filter oil thus reducing it's efficiency.

Even K&N states that the filters work better the dirtier they get.. So does my fuel filter until it clogs up. For the rest, see S2kracka's post that I copied below.

From AMSOIL Corporate Data

Absolute Efficiency
AMSOIL Ea Air Filters are the most efficient filters available to the car/light truck market. Ea Air Filters’ synthetic nanofiber media removes 5 times more dust than traditional cellulose filter media alone and 50 times more dust than wet gauze filter media. AMSOIL Ea Air Filters have a service life of 100,000 miles or four years, whichever comes first.

Information is also available comparing Bracket Foam Filters and Challenger (K&N) in aviation use... Same medias but I figured some people would say, in a whiney voice, "But that's for a Plaaaane", same same..

I use to work for a company that sold K&N, AEM, RACOR and various other performance filters along with AMSOIL.

I had a chance to go to a several day school at RACOR who builds some of the top filtration systems. Some of RACOR's marine filters are wetted gauze made by K&N and say right on the box, "For Marine Use Only". I had the opportunity to ask some questions so I asked "Why Marine Use Only?" The answer ... "There is virtually no dirt on the water, we just have to worry about the big chunks in the engine compartment and arresting flames"
