Engine/Transmission (1998.5 - 2002) anyone been denied warr because of K&N

[MCharlebois]

my VP44 is dieing-truck goes in on tuesday

Don't give them the chance... ... throw in a paper element. Dealers can deny warrantee if they choose to be real snotty. :-{}

I agree - while theres NO WAY the K&N could contribute to your problem, eliminate the issue and reinstall the stocker...

when I bought my 2000 the dealer specifically said "No K&N air filters". I have no idea why. I have had one on my Jeep for years without problems.

Especially strange - since around that time Dodge dealers were offering a "performance" air intake system designed around the K&N filter...



Sorta wonder if Cummins objected to the competition with their Fleetguard filters...

K&N makes a wonderful rock screen for a turbocharged Diesel!!



Ran them on all kinds of gassers, not impressed on the Cummins.



Say Dan, ever run an oil sample?

 

[Hillbilly Hotrodder]

Cummins' web site specifically warns against them, so I'm not going to give them any reason to risk my warranty status myself.

Come off it Gene you've seen MINE with the K&N - or do ya wanna see it AGAIN?...



(edit)



AH, ta hell with it here it is, might as well save time and confusion:





#ad




6500 miles on the oil in this analysis, mostly towing, full Banks setup, tweaked pump...



Be aware this was the last of 3 nearly identical oil analysis on my old '91 - all at at 100,000 miles or so - with a "nasty old K&N", "snakeoil STP", and an "idiotic" toilet paper oil bypass filter... Only just recently reached enough miles with the '02 to start getting reliable, settled-in readings, but will post those too as they occur.



NOW here's the challenge for ANY who wanna take it - put in a new crankcase full of YOUR favorite oil - synthetic or otherwise - use whatever additives YOU choose - or none at all, and use whatever bypass and air filtering setup you want - then let's compare analysis results...



No fancy footwork here, no "50,000 miles on the oil with extended drain, divided by X" tapdancing - simply put in 3 gallons of yer favorite oil, DRIVE 5-7000 miles, test the oil and post results!



Shucks, that's even easy enough for a sledpuller to handle...



Any takers?

Hate to agree with you ( :-laf ) but *my* silicon was 34PPM with a K&N and 7PPM with a paper filter, problem solved for me. By the way, it was properly oiled.



Gary, all your report proves is the K&N works with California dust not real world dust

"Gary, all your report proves is the K&N works with California dust not real world dust"



HEY, you might have a point there!



Using my truck mostly towing a 5th wheel, we HAVE been all over the US - including Texas - been thru a few dust storms in the process - but I'm sure the REAL test is constant off-road type use.



I have NO illusions as to the K&N being the "best" air filter - only that it is better than most critics give credit for - I personally think a BHAF type is the best way to go for no-doubt-about-it air filtering, and may well end up with one myself...

I have talked to Cummins and they STRONGLY say not to use them something about the amount of air they allow thus they aren't filtering as good as a paper element with the foam, as the manufacture says. I don't want to risk a $5000 engine for a little bit more power. Just my opinion
