You gotta love Rand.

I agree, that Amsoil graph on its filters looks like something a third grader did...in the dark...with sun glasses.

Poor to Greater is not a 'scientific' method of comparison.

The Truck: 1997 Black F-150 Flareside. Regular Cab ORP and Towing Package
The Mods: K&N Filter, Eurolid Hard Tonneau, Profile Windstream Side Deflectors and Lund X-Terminator Bug Deflector.

Okay here are the numbers

1. Resistance to flow measured in inches of H2O or Mercury!

Air Flow @ .25" of H2O

K&N E-1500(off road service)--100 cubic Feet per min.

K&N E-1500--280 cubic feet....

Amsoil TS-31-- 200 cubic feet...

Accel 71109-- 200 cubic feet..

Fram Ca326-- 80 cubic feet...

=============================================

Filtration Effeciency

1 How well the filter removes contaminants from the air stream
2 Percent removal used in air filtration refers to a broad range of particle sizes
3 Air filter efficiency dramatically changes over the life of the filter.

K&N E-1500 94.9%
Fram Ca326 99.4%
Amsoil TS-31 99.5%

I am trying to find information on the exact test method J726C
From what I know this is the way they test restriction and Air Flow.

=============================================
Life expectancy of a filter(minutes it takes to reach 5" of H2O)

K&N 10.8 minutes
Fram 19.2 min.
Amsoil 37.4 minutes

Now minutes that it takes to reach 10" of H2O

K&N 12.5 minutes
Fram 25.5 minutes
Amsoil 44 minutes

=============================================
Please bear with me I am not an engineer. I am going off of what information that I have.

I don't know what kind of contraption they use for this test but I have a picture that kinda shows a measurement before the filter and then again after the filter and they take a reading. Then they introduce a common media to increase the restriction(this is some kinda dust material) then obviously the more the filter begins to plug up the more restriction you have.

As far as my analysis goes I should have been more specific!

I was using Castrol syntec oil with 2100 miles on the oil.
I used the fram TG2 (tough guard)

18 ppm silicon is a normal number. As I was advised that no corrective action was needed

Now when I took the sample on my transmission the silicon level was 114 ppm. which indicates high levels of dirt.

At the end of this year I will post another analysis. Since I do one once a year with my oil change!

Sorry, your right! I was workin up a good foam there! Had a crease in my shorts... Heck, youda thought my wife sh*t in my cuff or something....


ANYWAYS! I would just like to see something really worth while for once. Some data that really knocks my socks off! I'm probably asking too much, but cheesey graphs and gossip can get unbearable!

I think we need people to ask WHY and question everything! If we didn't we'd all be little drones buying everything we hear.

Remember I'm not pissed, never was! Just a cracker who never knows when to quit!

I'm usually as happy as a skunk eatin sh*t out of a hair brush!

Msparks,

Where did these test results come from ? An independent test facility or the Amsoil site ?

I see that you were using Castrol syntec oil. I thought that you used Amsoil exclusively ?

 

Thanks MS Parks...

Funny thing is, Amsoil DOES NOT MAKE A FILTER FOR A 5.4!!!!!!!!!!!
At least not for my 98 Expy.

 

Fordbigfoot,

The actual numbers are from Amsoil for the filters. I went to a training class and they went over and explained the tests for the air filters.

The syntec is what I had in Before I switched to Amsoil. I used that as a baseline, so when I do another analysis in 1 year when I change my oil we will have something to go by.

I didn't publish the analysis because it really doesn't say much. Seems when I have another to compare then it would make more sense.

Rand,

They don't make the cone style yet. Something about patents and such. I don't know, but when I went to the training school in April they said soon. Every time I call up to Amsoil I ask, I would like to get the foam and then be able to compare myself.

I really don't think that there is much of a difference in Air filters. Just that K&N has lower initial effeciency, when I called K&N they said that after the filter gets dirty that the effeciency goes up around 98%. So just as long as your don't clean it too often you will be alright! I have yet to clean mine in over a year. I did reoil it a little this spring since we get so many dust storm down here I didn't want any dirt to get through.
I checked it a few weeks ago and it seemed like it was doing a good job!

 

Rand:

No problem. I am fairly new here and don't know everyones posting style/personality. I agree that we should question things more. It is the only way we learn and can share what we learn.

IT'S ALL GOOOOOOD!

 

If I didn't have a K&N on my truck right now I would question the validity(sp?) too. But since I do. I have no qualms about posting information about their product. I belive that K&N makes a great product, but the fact that the Amsoil filter has better initial filteration effeciency and close to equal air flow to the K&N and way better air flow than stock. With the ability to reuse the filters K&N vs. Amsoil being equal. I would choose the Oil wetted foam over the K&N. I have never used the Amsoil filter so I cannot speak from experience. But I do have 3 folks using the Amsoil filter in their F250 PSD's and they love them.

Will I ever get rid of the K&N? Hmmm I don't know if Amsoi comes out with the cone type for my truck I will get one and compare. then I will post my data here on the internet for all to see. That really is the only way.

Here is something from actual experience..... On my truck I *was* using a K&N filter.. truck ran great. Then all of a sudden the slightly rough idle and a "ping" at WOT around 3,000 rpm started to appear. I was stumped and was at a loss because I use my truck to pull trailers and need that rpm. I work at a Ford Dealership and asked some of my co workers in the shop what they could suggest. AS soon as one mechanic found out that I was using a K&N he said that he would bet that my MAF sensor was dirty... After consulting Oasis we determinded that dirt or Oil contaminates the MAF sensor And that would cause my problem. Sure enough after we cleaned the MAF sensor the Ping stopped! I was always very carefull NOT to over oil and only cleaned according to the instructions. I am back to paper untill another Idea comes about.

Thinkin seriously about going back to toilet paper myself!!

 

How do you clean your maf sensor?

 

You clean it with "Windex and Q-tips or pipe cleaners". Some carb cleaners, etc are not compatible with EFI systems. Never use one unless you read the can first. O2 sensors, etc can be damaged and just cause more problems.

I think before everybody gets all ticked off and throws their K&N in the garbage you have to take one very important fact from that article into consideration. This guy said that he's testing K&N's for a mining company who goes through numerous filters on each vehicle each week. Obviously these vehicles are being used in very dirty, dusty conditions. I don't believe that anybody on this site would be exposing their truck to any of these conditions. Even if you off road, you're not out there everyday all day long and you're probably not kicking up nearly the dust and dirt that these vehicles kick up all day long.

Would spraying intake cleaner in there work?

I've taken my truck through dust that was choking the people driving them, and clogging paper filters, down in Baja. The silt was so thick we had to leave 80-100 yds between trucks just to see. If the K&N wasn't working the truck would have been toast.
As a side note.... look at what the majority of the off road racing crowd uses for filters. If the K&Ns weren't working, the big budget racing teams wouldn't use them.
