Amsoil air filter..vs..K&N air filter

[PZicha]

Has anyone tried both ,which do you like better... ?????

There are over a hundred posts on this topic, do a search and i am sure any and all questions you have will be answered. Its really only K&N vs Amsoil if you are keeping a stock airbox. Thats the only filter Amsoil makes for the Ram. If you want performance upgrades and want a Psychotty or a Jannetty "Cold air" kit you HAVE to use a K&N. There is a new compnay called AFE who is making a K&N clone. It basically a K&N with thicker screen which to be honest with you, is a pointless reason to buy it. The only purpose of the screen is to support the gauze. It does not do anything for filtration. Your not going to collapse a K&N either. I have seen them mounted on top of a 14-71 blower and they did not distort. I have used K&N's for over 10 years on everything from Racing bikes, jet skis, cars, trucks, motocross bikes, etc and NEVER had a problem. If it aint broke, dont fix it, and until i see firsthand proof that the AFE can do something the K&N cant, i am not going to use them. Just my opinion.

EMDDIESEL, The K&N RE-0880 filter will collapse ifyou seal off the back side of the Psychotty housing. I destroyed my first one doing this. I have the AFE filter now and it hasn't deformed at all. The AFE filter has more filter material between the screen. I am very impressed with the AFE filter.

Why would your Psychotty ever be sealed?, even by accident. Seems like a strange reason to buy a different airfilter. And if you sealed the Psychotty on one end, the PSYCHOTTY should collapse, not the filter since the filter itself is INSIDE the psychotty. Not to mention, the rear of the Psychotty is designed to allow air to enter should the windshield cowling be blocked by snow.

Something else must have happened to your filter. A 14-71 High-Helix blower (which puts out over 60psi of boost) and pulls ALOT more suction then the Cummins ever will uses a K&N in the fuel injection hood and it uses throttle butterflies BEFORE the K&N. So if what you say about the filter collapsing when you blocked the Psychotty inlet, then technically every time you let off the throttle of this blower equipped engine, the K&N would collapse, and it does'nt. So your K&N must have gotten damaged some other way. I know just getting my K&N into the Psychotty housing dented it and distorted part of the screen, maybe that is what you saw. Either way, it in no way affects filtration. As mentioned, the screen only serves to hold the gauze, it does NOTHING to filter the air.

i've had both

On my 98. 5 I had the K&N, on this truck I have the Amsoil. I think the Amsoil filter "looks" a little more durable, but to be honest, If I hadn't pulled a homer and left my k&n in the old truck when I sold it, I'd have put it in the new one. DOH!





ps... they both kept the intake tube and impeller blades spotless... the key is to making sure you get a good seal. This is the one area I think the amsoil has the k&n beat, it uses an oversized foam lip to seal the box vs the grease on rubber the k&n uses.

Somewhere in TDR I read that K&N doesn't pass the Cummins air filter test. Does the Amsoil or AFE pass the Cummins test?

My dealer sells K&N filters, so if they are not approved, there is no way they can void your warranty since the dealer is selling them.

Tried both, Amsoil my pick

I ran an RE-0880 last year and it let a lot of fine dust through. For the most part I think K&Ns are good because many run them with no dust getting through and low silicate numbers on their analysis to back them up.



However I don't think the quality control is 100% and there are quite a few bad ones out there. Also, with the extremely fine dust in this area, the K&N had a hard time stopping everything.



As soon as I went with the Amsoil and reinstalled the factory airbox, the dust collection inside the intake disappeared, much to my relief.



There was a great thread (VERY LONG) on this subject I started last year "K&N Doesn't Stop Dirt!!!!" but it has vanished Apparently all posts before Dec. 2000 are either inaccessible, or GONE



BTW the SEARCH feature is next to WORTHLESS I want the old one back!

I have never had problems with dust infiltration, but dont forget you can always get the 25-0880 pre filter and you will have more filtration then the Amsoil.

 

[telong]

I have a K&N in mine. I like the performance, but I have to agree with dmurdock on getting a good seal. Some time after I put mine in, I removed the baffle ring from my turbo and noticed some dust build-up on the impeller blades. I've redone the grease seal since then. As far as not meeting Cummins specs, I don't know. I got mine from my Dad who works for an authorized Cummins Dealer/Repair shop in PA. They sell the K&N's as a performance replacement for the Fleetguards. I do know a lot of guys in my area that have the Amsoils and swear by them.

I have a K&N OE replacement filter in my Air Bulldog/OE induction system. It has worked extremely well for me, providing me with EXCELLENT oil analysis results. Prior to that I used a K&N RE-0880 cone filter, with and without the Psychotty system. Prior to the Psychotty, I used a K&N 25-0880 foam pre-filter over my cone filter (a. k. a. the Scotty system).



That said, for no particular reason I'm going to an Amsoil OE replacement filter once I install my NEW (modified and tricked out) Air Bulldog induction components.

Size for size, the Amsoil filter will out flow a little bit, and out clean WAY better.

To get the K&N to filter as well as the Amsoil, you need to put the foam pre-filter on it. Guess what happens to your airflow after you do that?

The dirt track racers around here call K&N "rock screen"



When you go with a filter as large as the Scotty with the foam, it should flow and clean adequately.



If you go with the Amsoil, be careful not to over oil it, it makes a mess.

Dittos to what Gene said

Do not over oil an Amsoil air filter. It makes a nice gooey mess in the upper part of the hose at the airbox side . What is nice is all of that oil congregates in the indented rings. I didn't see any oil past the second 'ring' and the turbo blades were dry and clean. Imagine rubber sealant that has laid in the sun for about 20 minutes and that was the consistency of the oil I was very careful about how much oil I put on the filter the next time I cleaned it. As for the K&N, I can't speak about it because I've never used one.

I'm not too thrilled about using a gauze air filter you can see thouands of points of light thru either! (K&N) Racer's use them. Right, and they rebuild engines how often? I think the OEM paper filter filters the Best as far as stopping dirt, it's just that the OEM's won't put a big enough filter under the hood! I think TWO OEM sized filters would filter better & flow as good or better than the K&N or Amsoil.

Thread is moving...

I'm tossing this one over the wall into the the "Products / Accessories" forum. It is the most "on" topic over there.



Thanks

PS, sorry about being slow in moving it. . I'm still a bit green at this new BB...

 

[BLACKRAM]

I have had both filters. The choice is to flow more dirt or flow more clean air. The answer is AMSOIL is far superior. There is zero difference in the way they flow air on a turbocharged engine. My temperatures were identical on both.

 

[tom sweeney]

i use an AFE cone filter,seems to work just fine. . at some point i may add K&N's prefilter on it just for kicks... . tom

Here is some pictures of my Ram airfilter using the Amsoil Foam Filter.

Only problem with an Amsoil filter is that it won't fit in a Phscotty. Scott who designed the Phscotty warns not to block off the lower end of the unit, it will collapse the filter whether it is damaged or not.

 

[drawson]

Bill, Scotty warned me about block off the bottom but I just had to try it. Now with the AFE filter I am see improvements from having it blocked off.
