Need 6.7L Air Filter Box

So, I threw this code and took my truck to the dealer. He told me my K & N filter could be the culprit and that if I didnt go back to an OEM filter it could void my warranty. P042E is for a stuck EGR valve. Before I bought the new filter, I ask the dealer where I purchased the truck new if a filter change would affect my warranty and was told no. I no longer go to where I purchased my truck because their certified techs quit and they cant do warranty work. Are they correct in saying that 1. my airfilter could be causing the sooting problem and 2. other than OEM will viod the warranty?
 
I don't know if they are correct or not but the painful truth for you to consider is they don't have to prove their position to void it. If you carefully read the language of the manufacturer's warranty you can decide for yourself if you agree with them but ultimately your opinion doesn't matter.

If the dealership voids your warranty it is void until you hire an attorney and get a judge or jury to direct the dealer or Chrysler to reinstate the warranty.

Why tamper with the air box or air filter?
 
I didnt tamper with it. It was simply time for an air filter and I replaced it, filter for filter. I asked this new dealer ship if a Fram or other filter from a parts store would be treated the same and his answer was if its not OEM it could void your warranty. So, far they have covered everything and I told them I would go back to an OEM filter but I dont get it. If a filter meets or exceeds OEM specs how can they void your warranty?
 
Hey don't worry about Harvey. He is a by the book guy. I think he does everything by the book. Not that theres anything wrong with that. But there is a lot to be gained by "tampering" with stuff on the 6. 7.
Getting better air flow, will not create more soot. Soot will cause an egr valve to stick, and a turbo to stick, and it's real bad for lots of things. But adding more air,,,, only cleans things up. not makes them dirtyer. The reason they tell you that it voids the warranty is because they don't know what makes things happen and/or what to do about them. so they blame it on your alteration, and tell you to put it back to stock or they will void the warranty. Most people go some where else, so it works for them.
There are 4 bolts holding the egr valve onto the intake. Take them out, remove the band clamp that holds it to the tube, unplug the connector and remove it. Clean the heck out of it and try to tap it a bit to see if you can jar the soot free. Re install and see if this helps. Or, better yet. delete it and the DPf and get a juice to clear codes, You will have a whole new truck and the codes won't come back. Then you don't have to work about the warranty at all. LOL.
Seriously though. Ask anyone with a 6. 0 ford. The vanes in the turbo get stuck all the time. You get at least one new turbo during the warranty period if you have one.
 
First the filter in itself will not void the warranty. What will is any failure caused by the filter. Most failures are caused lack of proper cleaning and oiling of the filter. This allows dirt to pass through it and causes "dusting", when the rings wear the cylinder to a mirror finish.

The biggest problem I think you have is the mass airflow sensor being upset by the K&N, resulting in the code. The system uses the mass airflow along with the O2 sensors to determine if the EGR is operating correctly. Upset the airflow and the sensor can't do it's job. So properly maintain the filter and ignore the light, or loose it for the OEM paper filter that does a great job by the way.
 
TDR writer Joe Donnelly has tested and reported his findings on air filter comparisons on more than one occasion over the years in the TDR magazine including one issue this year. Joe has a Ph. D. in chemistry and knows how to conduct scientific tests.

Joe's testing has reported NO GAINS in engine performance in a factory original engine and only very modest gains in the range of perhaps five horsepower on mildly modifed engines.

Some of the aftermarket air filters with good reputations don't filter as well as the OEM air filter regardless of the advertising hype or don't seal as well in the air box.

Aftermarket air filters are like placebo medications.
 
If K&N filters are anything like they were ten years ago, you might as well not
bother with a filter element at all. I was foolish enough to buy one for my '88
Landcruiser. After about a year of use, the tube from the air cleaner was full of
grit that was never filtered out. Their filters used to be a screen with oil soaked
flocking, and maybe still are. It's a worthless system that should never have
been allowed on the market. If I was a dealer, I would void the warranty for
any K&N air filter user as well.
 
A K&N Drop In filter is supposed to be considered an OEM Replacement, just like wix or fram. That silly act(the one I can't spell and don't feel like looking up) is supposed to protect people from warranties being voided when a stock replacement part is used. Contact K&N and they are will help you with warranty issues if you use a drop-in filter. If you have a CAI or modified the box your on your own!

By who?

Certainly not by the companies who design and build the engine and the truck and and provide the warranty. Cummins and Dodge don't consider a K&N filter an OEM replacement.

Good luck on trying to get K&N to pay for a replacement engine when it is trashed.

The name of the federal law that you referred to is the Magnusson-Moss Act. My spelling is probably not accurate. But printing that law out and taking it to your dealer who voided your warranty is as useless as an autographed photograph of Nobama. The dealer will laugh at you.

The federal law on product warranties will not do you any good unless you are prepared to pay to have professional engineers disassemble and inspect the engine and report in writing that the air filter did not cause the problem and hire an ambulance chaser to file a lawsuit and represent you in court. Count on Dodge and or Cummins to have better lawyers and better experts to testify. A case could drag out in the courts for years. Even if you should eventually get lucky and get Dodge to settle or win the lawsuit you would have spent more money than a new Cummins reman would have cost you.

The only place puffing up and demanding your rights works is on internet forums. In the real world you are unlikely to win.
 
Oh my gosh! This is so not helping.
BDW, you have a stuck EGR. You can do one of 2 things. Get yourself a Juice w/ Attitude, and block the egr valve and unplug it. Or pay someone else, or do it your self, to clean the thing out and get it working again. I personally would, and DID, do the juice and blocked the emissions. You will get ,,,,gauges, cold eng protection, turbo timer, performance, better fuel economy, and can do a DPF delete. You will also know each time it goes into regen. Clean,,,, and I mean Clean oil, better performance, and your engine will last a lot longer.
I did it and will never go back.
Just my 2 cents, but at least I'm not ragging on you about your choice in air filters.
BTW, Cummins will also void warranties for a K&N filter. They do dust your engine, but it is a mute point cause it has nothing to do with a stuck EGR valve.

I am not saying that every aftermarket part is an OEM replacement, but K&N will stand behind people that use there OEM replacement air filters. It is actually part of there warranty. Call them and they will fight for you. I don't know how far they will go but they will stand behind there product. I know K&N gets a lot of crap on this and other forums but they do stand behind there products.



Not condoning the use of the filter or other aftermarkets parts or arguing what is OEM replacement or not. Just trying to give Brian a route to help protect his warranty.

PFranzese,

I know you are trying to help the original poster and my purpose is not to discredit you. I don't think it helps anyone to further the myth that K&N or any other aftermarket manufacturer is going to warranty anything more than their own products. They will not.

If you read K&N's warranty very carefully (why not post it here?) you will see K&N only warranties their own products while providing some carefully weazle-worded language written by lawyers to create the impression that they will somehow back you in the event of an engine failure.

Let's be honest. Common sense should tell us that K&N is not going to pay for a replacement Cummins engine and they are not going to have any influence "fighting" for you with the OEM. If push comes to shove you will find that they are actually going to provide nothing more than a refund of your money on the air filter and empty promises over a phone.

As I have written many times, it is not my concern how others choose to modify their trucks. I don't care. What I care about is truth and facts. I want those who actually seek factual information to be informed. If other TDR members know the facts and still choose aftermarket products it is their money and their choice to make.

I disagree with anyone who believes or claims that if they replace OEM parts with aftermarket products and failures result the cost of repair or replacement is going to be covered under the OEM's warranty or the aftermarket manufacturer's product warranty.

A few dishonest dealers will overlook modifications and help you defraud Dodge by passing the repair or replacement costs back to Dodge but when expensive parts like a complete engine is required I think you are going to find a Dodge service rep standing in the service bay demanding to see the engine and know the cause of failure. I think we can all agree that a Dodge dealer who sold, installed, or overlooked aftermarket parts is not going to replace an engine at their expense.

I understand what you are saying, from an OEMs standpoint I can certainly see why they and others wouldn't consider K&N a factory replacement part. That is why I have decided long ago NOT to use one in my own truck or any other mods as well. I certainly don't condone ripping off the dealer or chrysler by being dishonest and simply calling K&N to see if they will stand by there claims that there filters won't harm an engine is certainly worth a try. They are the ones that state that their filters won't harm an engine so they should stand behind that claim.



The warranty is long and lawyer like but also states that they DO warranty more than just there filter. I am sure that there process to have them warranty something is long and a pain in the *****, at its best. But they make the claim so I would at least call to see if they back it up. If not I would never buy or recommend someone to buy there products.



K&N Product Warranties
 
would someone please tell me how a K&N filter could possibly cause an EGR Valve to stick???? This thread is soooooo far off the problem I can't believe it.
 
I am not sure how a K&N or any air filter could cause EGR and soot issues but one of the questions in the original post was about voiding his warranty due to an aftermarket air filter. It would be nice to hear the dealers explaination of how this can happen but I am not holding my breathe for them to post up here.



Harvey

That was really what I was trying to say, which I usually fail to do clearly 90% of the time. It doesn't hurt to try, if they come thru and help he is ahead if not he is in the same place, maybe one or two phone calls extra.
