k&n air filter

[Diesel Freak]

well, I have a Dual Element K&N on my truck... . no oil on the turbo, and no dirt gets through. I will never have to clean the cotton gauze.



So neener neener!



My secret?



Maxima FFT!



I think I need to put a warning in my filter so no one touches it and gets the sticky goo on their fingers.

 

[Ram4Sam]

Glad you got over it....

Dalton, glad you got that act of niceness over with quickly. It's really not you and when I read it a second time, I got kinda of quesy! The weather here is has been great, thanks for asking Just a couple of weeks ago I got to sample your wonderful weather. We had a couple of hours layover in Houston, on our way to and from New Orleans. The humidty was pretty bad there, experiencing it first hand helps me understand your wit and personality And how about that Steve M guy, do you supppose he got a K&N from the same batch that yours came from?

P. S. Did you hear that Dr. Performance has endorsed the BHAF! :-laf

I'm gonna make a new high flow air filter soon, it will be made out if 1/4" wire mesh to keep the birds out and use grease to attract the dirt, that way there will be no oil to migrate.



I will pay $50 to everyone who will use it.



Wonder if people will argue about if it works or not?



I run a K&N and you dont. What difference does it make as long as we are happy?



Actually, this thread is kinda fun

 

[RADdodge]

Oh no, Not More - OR - I have too much time on my hands

I wasn't going to comment on this thread. I use an AFE filter so I fall in the same ballpark as the K&N crowd. But I ran across this paragraph on the Cummins’ site and thought it was interesting. FYI.



“Does DaimlerChrysler authorized the use of high-flow aftermarket air filters such as K&N with my Cummins engine?



No. DaimlerChrysler and Cummins do not recommend the use of increased flow air filters such as K&N, because they can allow contaminants into the intake that can ruin an engine (scoring the sides of the pistons, etc. )”



The above quote was from this site:

http://www.cummins.com/au/pages/en/products/dodgeram/faq/index.cfm



So I guess they had some problems and their lawyers are trying to CTA. Key word was “can” allow contaminants. Any defective filter falls into that definition. So in essence, according to them, K&N filters and the like are defective. Anyway, a person is going to do what they have to do. It would be nice to know the truth so as to make a good decision. So what is the truth, or is it that some just can't handle the truth (I think Jack Nicholson said that – has a nice ring). Or is it less profit to those who sell other types of filters. Or ad nauseam. I don't know, and I don’t have a strong opinion one way or the other. The facts seem to be that K&N filters (and the like) have had instances of failure that threatened DaimlerChrysler and Cummins profitability (i. e. repairs at their expense). I’ll turn over the soapbox now. Flame on….

I've never owned a K&N filter. I don't doubt that they flow a lot of air. They might very well be good filters but I'm not having any problems with my warranty in tact paper filter. My problem with K&N is not with the filter. It's with K&N's misleading warranty. I can handle the truth. The truth is K&N does not stand behind their product and they state that truth in writing. And that's the truth.

 

[Ram4Sam]

HHHHHUUUUUUUUUUHHHHHH!!!

Okay Steve, see if I have this straight. You don't own and never have used a K&N filter. It has never let dirt into your engine and has never threatened your warranty with Dodge, but you think they might actually be a good filter. The company tells no lies in it's warranty, it is very clear that they won't pay for any damage caused by their product. Then you say they have a misleading warranty just because they are so honest. I'm lost



Where's Dalton, things are so much clearer to me when he explains it.

K&N verses Afe BHAF

I heard all about the K&N debate over the TDR threads. I took my K&N off to install the Afe unit after hearing about the Cummins statement. I have a question though? The Afe filter, I was told was developed by a person who use to work for K&N and the Afe was a better unit in every way, flow and filtration. Well I have had the Afe MEGA BHAF type unit on my truck and have not seen any dirt or oil down stream of this unit yet at 13k mi. No oil sample data yet though. It sounds like the oil testing is the only way to know. I'll do that now after this debate. Any opinions?

 

[Steve M]

Ram4Sam,

The warranty isn't spelled out on the box. It simply says it has a 1million mile warranty. That's deceptive. Then the BS about the Magson-Moss warranty act. More deception. Yes Chrysler and Cummins can void your warranty if an aftermarket anything that's not approved by Chrysler or Cummins causes damage to your engine. Fram oil filters aren't approved either. But at least Fram stands behind their product if someone does insist on using them.

I don't know if a K&N is a good filter or not. It might be but thier warranty says they don't have enough faith in it to put a decent warranty on it. They're not willing to take the gamble on it but you are?

If you want to use a K&N filter on your truck, I won't lose any sleep over it. I just felt inclined to explain why I haven't and won't. It seems pretty clear to me...

 

[GSchlegel]

This discussion comes up every 6 months or so. Each time I throw in my $. 02 worth. My truck now has over 150,000 miles using K&N air filters. I reciently went from the airbox filter to the RE-0880. I have checked the turbo blades and ducting several times. No oil or dirt. It is so dry the silencer ring is showing signs of corrosion! The oil consumption is the same now as it was when I got her with 20,000 miles.



What is wrong with that? I am supplying my engine with more clean, dry air. I have lower EGTs at increased fueling.



How many of you that are arguing about air filters are going to put 200, 300, or 400,000 miles (my goal) on your engine?

[JConley]

I talked to Cummins a while back, and as soon as I mentioned K&N, the tech on the line said "Dont use it" Thats good enough for me.



Its your truck, use whatever you want.

 

[Ram4Sam]

Stevie boy.......

The last thing I was trying to do is convince anyone to switch to a K&N. Especially you since it is evident that you have made your mind up about them and I would hate to confuse you with facts. I just find it a strange occurrence when you jump into these K&N bashing posts with both feet and have never even bought one.



Sam

 

[Steve M]

Ram4Sam,

There is no confusion. I understand K&N's lack of a warranty very clearly. I don't need to buy one to realize that they are a gimmick with no warranty. But they do come with a cool sticker!!!

I've never bought a prostitute either but I know the fact is, there's no guarantee you won't catch something from her.

You can gamble with your truck if you want to. I believe Cummins knows more about diesel engines and diesel engine filters than you do. I'll take their word for it. The fact is, I can't go wrong using a Fleetguard or Mopar air filter. They give the engine more than enough clean air and keep my warranty in tact.

Fact: NASCAR uses paper filters. Not K&N.

 

[illflem]

To each his own. I don't think a power box or fuel plate is going to do much for your warranty either. If you don't need more air just use a stock filter.

 

[Ram4Sam]

UNCLE! UNCLE!

Steve, your chicken little, the sky is falling outlook on this is too much for me. I give! Good luck with your crusade to save the world from these dastardly filters. Oh, and have a good day!



Sam(aka the gambler)

 

[rrausch]

I've run a K&N in my '95, bombed 2500 for over 50,000 miles and no dirt, no oil has shown up anywhere. If you overoil the filter, of course it will get sucked off and show up downstream. Those little holes are actually covered by oiled microscopic cotton fibers, which filter just fine. That is why the K&N flows more air. In a paper filter, the air has to change direction, zig & zag, as it goes through the paper, and the dirt, being heavier, plows into the paper, getting trapped. In a K&N, the oiled cotton attracts the dirt, instead of having to trap it as the air zips around.

 

[Steve M]

Ram4Sam,

Give me a break man! I'm not out to save the world from K&N. I said I won't lose any sleep if you use one. I stated that I won't use one and the reasons why.

I going to take my Harley out and get some breakfast. It's 0700 here. Ya'll have a nice weekend!

 

[rrl989]

Speaking of prostitutes, I paid $60 for the K&N a couple of years ago only to find out that it does not provide a good seal when inserted in the box. If I'm paying all that money for increased performance, I'm not about to use any any kind of jelly or sealant to get what I already paid for !

[illflem]

I've seen a few stock paper filters let dust though around the edges. If I were to use a paper filter I'd probably use some kind of jelly or sealant on it's gasket also.

 

[TURBOs4LIFE]

"quote" Second, Turbo fan blades do get dirty and do turn black with the very fine dirt that passes through paper air filters as well as K&N filter.





All filters let some dirt by even the best filters (HEPA) let dirt through! The reason you see dirt on turbo blades and such is be cause of the clean oil on the back side of the K&N being pulled off from over oiling. This oil is very sticky and will stick to anything!

Now you have a very thin tacky residue on your turbo blades. As the "NORMAL" dirt passes (remember all filters pass some dirt) through it sticks to the blades. The reason people who use paper filters dont see this is because they dont have a sticky residue on their blades and the "Normal" passing dirt go right passed the blades without sticking.

 

[Shovelhead]

Just wondering how much of the "dirty, oily" turbo problem might be caused by "Barking" the turbo?

Opinions?
