Engine/Transmission (1998.5 - 2002) K&N filter voids warranty???

[John Berger]

No, no oil war

A member pointed out the API web site on the last oil war. It listed a ton of oil manufacturers that have certification and can use the donut. Amsoil was on that list and a grade of 15W-40 was also there. I'm not sure that's our diesel oil, though. Believe me, I don't care what you use. It's your money, it's your baby, it's your choice. But some of their oils are API certified as I understood the information on the API website.



Here, check it out:

No oil war is intended, implied, suggested or otherwise being manifested in any form on this earth or in the next dimension Oo.

I have read before about Dodge and Cummins not recommending the K&N. Supposedly Dodge dealers were supposed to pull the K&N for the CTD.



For me I switched yesterday to the BHAF. The latest TDR gives the flow rates for these filters and it flows a heck of a lot more than the K&N. My . 02.

John,



That's my understanding as well - some are, and some aren't. Those that are can carry the API donut. Those that aren't cannot. If this is important to a user, he/she should check the bottle to see which category that particular oil falls under.

2 of the Dogde dealers i go to sell K&N filters. They even said if a K&N filter was the cause of engine failure if you were to put your stock filter back that they would have no way to prove it and said DC would not hire a forensics team to confirm which filter was installed at the time of engine failure. It is'nt just DC dealers that are incompetent, i have had similar problems with Chevy dealers. I had a front axle leak in my 95 Tahoe and after i brought it into the dealer and said "Its not the axle, you did'nt tighten your oil filter and its motor oil leaking". How stupid do you have to be to not know the difference between engine oil and gear oil?. I went down to the dealer and pulled the front wheel off in the parking lot and showed the leak at the axle seal and asked them to show me where there is motor oil leaking. Guess what, they could'nt. Another case of a dealership that has no brains, only people who read shop manuals and try and cheat there customers.

I think this was mentioned before, but does anybody here realise Cummins owns Fleetguard?. Ya think that MIGHT be one of the reasons they dont want you using K&N filters?. Lets say 25% of ISB owners use K&N filters, that is ALOT less people buying Fleetguard air filters. I am 37k miles, K&N RE-0880, Amsoil oil, dual bypass and FLAWLESS oil sample results. Thats all the proof i need.

Instead of pouring the heat on Cummins and Chrylser, why don't the K&N fans put the fire under K&N to guarantee that their filter will not damage your motor? The best filter in the world should have the best warranty in the world.

Does anybody know EXACTLY what test Cummins uses on air filters? I think it's a more stringent version of the SAE test but I'm not sure. Also, I believe the SAE standard that K&N tests against is for the MEDIA not the particular application - meaning that the oiled gauze may work fine but the sealing of the DC designed airbox may leave something to be desired. Anybody know if Cummins has tested a complete Dodge CTD intake system per their test?

I also run the RE-0880. My last sample had a high silicon reading. I also fixed my dowel pin on this same oil. I used high tack and the gasket instead of rtv silicone. Would the high tack give me that reading also? I really like my K&N.

i e-mailed K&N over a week ago and asked them directly about if there has been any problems with the cummins and if K&N had been a cause of it... . also asked them if they guaranteed the K&N air filter would do no harm to the cummins... as of today, i have received no answer..... wonder why... . are they too busy or is just one puny little question not worth going to any trouble over... ??/

Here's your answer. Read it carefully word for word. They state in writing (not on the box of course) that they will not stand behind their product if it causes damage to your vehicle for any reason.

Steve,

That is pretty much standard for all aftermarket equipment. Just about any product warranty says that it will not cover consequential damage.

The silicone sealer would probably not cause a high silicon reading unless it was being leached into the oil. However, you performing the KDP repair and opening up the front cover and potentially getting minute particles of dirt (silicon) into the oil system could be a logical source of increase in this number.



On spectrographic wear analysis, you are looking at particle sizes less than 10 micron in size. (most people can only see 40 micron, so it's very very small particles!).

I just talked to my local dealer, they told me that K&N filters were fine. I was told that a filter is a filter. He said it's not a mechanical part, so it doesn't void the warranty. He did say that one of the diesel techs at the dealership put one in his truck and got a some service codes poppin up, but he said that was just on that one truck, many others run K&N Filters with no problems. He told me to run with it. My suggestion, ask your servicing dealer what they say.
