K&n filter?

[CDenton]

Hi

I have head you can't put a k&N filter in the 6. 7. on the 2010. Is this BS or is it the truth. they say it will make the engine lite com on.

Thanks

Save your money and your engine, stay with the stock filter. Hold a K&N up to the light, you can actually see through it.

Another member posted my favorite answer to the K&N filter question awhile back. He recommended buying a piece of window screen instead. He said it was cheaper, easier to install, and filtered just as well.

To me K&N spends more money on advertising then on design and research. Their products are not up to par with other aftermarket products. You are paying for a low quality product that the uninformed will purchase, thinking they are doing good.

If you want to throw away your money, I take it.

For your answer, read the posts in this thread by TDR member sag2, who is a very knowledgeable, experienced, and honest Chrysler/Dodge service tech about oiled reusable air filters such as a K&N:

In the past I used K&N filters a lot, in motorcycles, used for desert racing and in a pickup truck. They worked well in the racing applications where they were cleaned and re-oiled each time the vehicle was used. In the pickup it was a pain because:

1. When the filter was cleaned it had to be dried before re-oiling it and the truck could not be used without a backup filter.

2. After a period of time the dust collecting on the filter seemed to wick away the oil leaving it dry.

3. If, while cleaning, water was sprayed under even the slightest pressure it caused the gauze material to separate leaving un-filtered air passages.



I gave up on them on any vehicle that was in daily use. In racing applications they need close scrutiny to insure there is no thread separation, in the gauze material, which would permit unfiltered air through it.

I think it was my favorite socialist, beheiting, who posts unbelievable comments over in the political forum that deserves credit for that clever suggestion. I liked it and used it without giving him credit by name.

1. oiled air filters and turbo chargers don't mix.
2. K&N = junk and the dyno against a stock filter will prove it.

Have a friend that works for Cummins and they do not recomend in fact they say NO to K&N so, as posted save your money, AND the new sensors, the plethora of sensors will tsend wrong messages when too much air gets in !!!

Thanks for all the help, you guys never let me down.

Thanks again

Don't really know what you guys are talking about. I've had an AFE Proguard 7 drop in air filter in my '10 since mile 1 and I'm now at 26,000 miles and have never once had a check engine light come on. Don't think I've run through a tank of fuel yet that I haven't been hooked to a trailer at some point on the fuel gauge. I use my truck for what it was made to do, "work". My last truck, a '96 had 280,000 miles on it when I sold it and it had a cold air intake from AFE, with their filter on it since 110,000 miles. also with no problem, and that truck was pushing 420hp. at the wheels! If the filter is maintained properly, I can't see why it wouldn't work just fine, and probably better than the stock filter. If you don't have first hand experience with this topic, then you are just guessing at what you think is the right answer to the original post. I've read many posts over the years and I really can't stand it when people make comments without first hand knowledge on the topic at hand.

Some of us know instinctively that the manufacturers build outstanding products such as filters because it is the manufacturer who has to provide the written engine warranty and pay for parts and labor when an engine fails during the warranty period.

We also learn from the negative experiences of others. I have a good friend who was a mechanic at a Dodge dealer. He has told me many times of the customers who brought their trucks to his dealer service department with trouble claims of oil consumption and blue smoke. He said the first thing he or the other diesel tech did was open the hood, open the air filter compartment, observe the aftermarket air filter, often a K&N, close it up and call the customer to tell him his engine was trashed and his warranty was voided.

Some of us have also read extensive tests in the TDR magazine performed by engineers and other professonals which prove without a doubt that aftermarket filters do not filter as well as OEM and do not provide any horsepower benefit at all.

Many TDR members have read the occasional post on TDR of a member who has tried it and found no improvement on the dyno and others which have reported dusted engines and denied warranties.

Many of us understand the fundamentals of diesel engines and know that removing the entire air box and filter does not increase air flow and even if it did, it doesn't do squat for diesel engine performance. That is gasoline engine technology.

If you choose to use that aftermarket crap on your engine feel free to do so, it is your right. But don't lecture the rest of us who know better. We're not buying your baloney.

After market stuff's

HMMMMM? Brought up a lot didn't we. Well there was nothing said about AFE products which are sold on Geno's garage, the orig comment was for K&N they, as stated spend more on pub than research. So with that said 1970 Cummins 220 HP for an over the road truck pulling 72,000 lbs ??? Today 350 HP in a pickup pulling 12,000 maybe 20,000 tops ??????? How much power do we need ??? 20,000$ worth of engine designed to run with a certain filter vs a "HiPer" filter with boarderline capacity ???HMMMMMM ???? Me thinks I'm gonna stick with the quieter factory spect'd filter, so I change it twice a year CHEAP ins NO? Bottom line Cummins, Ford, GM, ETC; all of these people spend millions for research and development tryin every type of product out there so as to give YOU the consumer the best value for your buck. So why mess with something that works. Put in it what you will and enjoy. :-laf

HB, I'm not going to waste my time with a detailed response to your comment, but you should be careful about what you say. I am really not impressed with your last statement!



and BTW "Baloney" goes with mustard, I didn't think it had anything to do with air filters. :-laf



You're the man.

YET ANOTHER REASON NOT TO USE K&N FILTERS: Member of my fire company had new 2009. Swapped a KN filter in there. Started having all kinds of DTC's. Seems the K&N red oil sprayed on the filter was getting scked through the filter and was mucking up the inline turbo sensors? Not to mention that the dealership then warned him that these K&N filters are prone to cave in, separating and dispensing filter media into the engine causing disasterous results. Lastly, he was then warned emphatically that his warranty would be voided if he persisted. He went back to the OEM filter and is much happier. By the way; he reported no increase in mpg as the K&N manufacturers were reporting.

The only thing I would add to this is the factory doesn't spend ALL of it's resources getting you the best of the best parts. Think how many pieces are sent out to a contract bid... Who gets the job? I would hazard that the lowest cost has A LOT to do with which vendor builds the part (track bars? shocks?). My original 2001 air filter box let so much dust around the edges of the filter I had to use filter grease to seal it up. Not the best of the best in my opinion. I think you'll find many aftermarket kits that offer better sealing, better flow and ALLOW for higher horsepower. An air filter will never ADD power, but a better set up will not hold you back IF YOU WANT TO ADD POWER TO YOUR TRUCK!

I have been to the K&N filter facility in Riverside CA it was about about 5 years ago, they do test all there products, most people that knock then have never had one IMO. They are a cotton layered oiled filter, they started back years ago for off road racing, if your getting oil in your intake, you didn't oil it correctly, they have instructions, if your getting dust in your intake you didn't oil it correctly. I have a Banks Intake on my 05, it has a cotton oiled filter just like the K&N, I use K&N oil on it, my intake is spotless, and there is no oil on anything, my 55 Chevy street rod has a K&N, same thing there, when I had my airplane, a Beechcraft Bonanza, it had a K&N, no problem there, so you can knock the K&N all you want, but if you never owned one, try to stop repeating all the conversation you read on web sites, it isn't true. Now with that said, the factory paper filters do a fine job, and when I get my 2012 Ram this year I will not be installing a K&N, because for what I will be using the truck for, I don't need one. I don't do oil testing on my truck, but when I had the airplane I did, and after adding the K&N air filter, the Silicone (dirt) in the oil was reduced, the stock paper filter looked like a car filter, 5x12, and about an inch thick, that is my test, it helped, I like there filters, but you have to have the right situation to require one.
