E-mailed K&amp;N about that availability of the K&amp;N and here's their response-<br><br><br>Dear Customer,<br><br><br>There is no replacement filter for your vehicle at this time. It is currently in development. Please check back in 60-90 days for a possible update. Also you can check our web site at http://www.knfilters.com/ it is updated every Monday with new products.<br><br> I read somewhere people already have them on their trucks? Hmmm...what gives? ???

 

:<br>AIRRAID now has a replacement air filter for about $55.

 

I would strongly recommend staying far, far away from oiled filters. Cummins has been giving us dealers a really hard way to go whenever we want to order turbo's. They are making us jump through a lot of hoops when it comes to turbo's, and if you are running an oiled filter, they are pretty much gonna void your turbo warranty. I've got two trucks in the shop right now with turbo problems and oiled filters, and if we send these turbo's back to cummins and they see all that oil residue, they charge us backforthe repair. It has happened before and it is getting worse with everyday. Sorry fella's to be the bearer of bad news. All I can say is, if you want the maximum power from your truck, get the 4.10 gears, and don't modify, unless your are prepared to pay for the repairs yourself. :'( :

 

Luke, I appreciate your comments, and have recognized you as an 'expert' in this forum. I guess w/ the turbo, it just sucks that much more air in??? Is that the problem? I run K&amp;N on my ATV with out an airbox....in the desert and never had a problem. Of course it's not sucking in near the amount of air.<br> Oh, I do have 4.10's ..nothing wrong with wanting even more power..I mean, I do just have the SO :. <br><br><br><br>Never heard of it...comments?

 

I think the problems Cummins has with oiled filters, is that there can be to many variables. If you under oil it, you'll not have proper filtration. If you over oil it, you'll be sucking oil directely into the turbo : All I know is they have been cracking down on us and I have been putting the word out. They are not going to cover turbo's if you are running an oiled filter. Now, some dealers may try to let this fly, but once cummins finds just one turbo with oil residue in it, they are gonna come down on that dealer with everything they have. And let me tell you this, I know from experience, &quot;hell hath no fury like the techline people at cummins if you try to pull the wool over their eye's&quot; :'( &gt;

 

Luke, thanks for your patience on the various threads when addressing these questions. It never ceases to amaze me how many people will pay this much for a vehicle and not bother to read the owner's manual. A few read it and seem to want someone to tell them they didn't really see what they saw?? I thought the 2003 owners manual was quite clear on this subject - use the specified filters or you are on your own for repair costs. I really have to sympathize with you on having to restate this so much... I will keep you in my prayers!!

 

 

Luke (or anyone who can tell me),<br><br>What is the failure mode in a turbo that is caused by oil on the blades, or in some other way contributed to by an oiled air filter?

 

Luke,<br><br> Another question about alterations and DC/Cummins:<br><br>What mods are allowed? Gauges - how do they feel about drilling a hole in the exhaust manifold for a thermocouple to measure pre-turbo EGTs? What about taping in to measure boost and/or fuel pressures? Would an aftermarket air system like a Scotty II be a problem (no oil on the filter)? Will larger tires cause some dealers to refuse to warrantee the drivetrain? Etc., etc., etc. ???<br><br> Thanks for helping to keep some of us out of trouble!!<br><br>F11Engineer

 

Having to deal with cummins warranty for years on big rigs....Ive found cummins needs to prove the part that was not spec'd was the cause of the failure...we proved this point when my company when to 40,000 mile oil changes they told us our warranty would be voided unless we used cummins blue oil...to make it a short story cummins couldn't prove their blue oil was better then Kendall SHP and they allowed our 40,000 mile oil changes<br><br>I know dealers have a tuff time with warranty thur Dodge Corp and could end up paying for a warranty repair if corp refuse's the claim and the dealer can't past that cost back to the customer...the problem I can't under stand is that LukeS said he's dealing with Cummins on these turbos I thought Dodge handled all the motor warranty with these trucks....LukeS could you clear that point up for me ??<br><br>Oil film on turbo blades is a petty weak excuse to void a warranty claim and I think they need to analyze this type of failure better there has to be more to it then just oil film causing a turbo failure....Bearings....forgein objects...parts failure...lack of oil ??.....A true statement is if you make any Mods to your truck be ready to pay for warranty repairs until you can prove your correct...Iam off my soap box now

 

I think what Luke was implying by his post was that oil on the turbo blades doesn't mean that the oil caused the failure, rather that the presence of oil indicated a filter other than the factory recommended paper filter has been used. It is fairly common knowledge (and by K&amp;N's own admission) that the K&amp;N filter does not offer the same filtration capability as the OEM paper filter.While Luke is not dealing directly with Cummins, D/C will forward a failed part to them for analysis and if they reject the claim to D/C, D/C will reject the claim to the dealer.<br><br>Hope this clarifies this point.<br><br>Mike<br>

 

Well I guess we all would be happier if the Filter Minder was not showing 30% when we drove it off the lot...whats up with that?? ???

I would never buy a used diesel truck if I saw it had been running a K&amp;N filter.

 

Ok, OK, I'm convinced. I'll continue using them on my other toys, but since a Diesel IS a different animal, I won't go the K&amp;N route. I do know for a fact that they're great filters on gassers though, as far as filteration and power. Very well...
