K & N filter change

new truck or older truck dirty filter or one that allows dirt through to engine ain't gonna discriminate based on age or how many sensors it has...

I understand that. I was talking about how the newer trucks won't work properly ifs they get oil residue on the sensors.

If I move a filter thawing a MAF fault to another truck the fault goes with it. Goes away with different filter on first truck. ITs not the Sensor.

I have thrown Faults with paper filters too. Driving in blowing snow the air box will fill up with snow and soak the paper filter.

We're one mile of gravel road to the blacktop from the house. Installed K&N's in Jeep Liberty diesel and the 2000 Dodge diesel (Edge with Attitude) when bought new. 272,000 on the Dodge, 74,000 on the Jeep. I clean the K&N's about once every 9 months. No dust past the filters. They work for me! But if I was the OP and after reading 10 pages of negative responses I'd be running to NAPA for the paper to.

So you are running oil analyst regularly and have verified that your K&N filters are not letting dust by? That goes for everyone. Show us your oil analyst reports. Or is your finger better than a lab on checking on this?

Why in the world would I run an oil analysis....NOW....on a 13 year old truck with 272,000 miles that runs like the day I bought it???????? And as for the Ram people not honoring their warranty if you have a K&N filter.........The Dodge dealer, where I bought the truck, sold it to me and the Jeep dealer where we got the Jeep sold us the K&N before we drove it off the lot. As for my finger test....it has served me just fine over my lifetime. The rest of this mumbojumbo is just that. Reminds of the sky is falling....the sky is falling...

Your truck is not the same as the new ones.

Ram can deny warranty if you use a K&N or oil type filter in a newer Ram with Cummins.

used Afe oiled air filters on my 2005 3500 CTD Ram for 250,000 miles or 4000,000kms, 90% of those miles/kms were on dirt/clay roads...lots of fine talc like dust...no issues. My nephew bought the 05 and continues to use it on the same roads. Proper cleaning/oiling and installation, no issues! As far as Ram or any other manufacturer denying warranty, they can use any excuse to deny warranty.

I did mention AFE is a better product.

Your 05 does not have the sensors that the newer 4th gen trucks have.

Yet again for the second time, per actual long term offroad use the K&Ns I have used needed prefilters to keep dirt out of the intake manifolds and the oiled gauze sagged and broke apart over time due to vibration and rough dirt road usage.

Oiled foam will not break down and sag with rough usage although they do wear with repeated washings and need periodic replacement but their filtering efficiency is second to none.

Outerwears recommended on all offroad filtering applications.YMMV

Most of my post wasn`t directed directly at you. only the fact that most of the people saying they are useless haven`t used them. we`ve always had the same thoughts, except now on this LOL! hopefully that`s all we disagree on!

Nothing personal on my end! And I'm jealous of your V10, definitely not your air filter.:p

It's not that the oiled gauze filters don't capture dirt in their sticky mess. It's that after they get loaded with dust, tiny particles of sticky dust break away and get sucked into the engine. This might not cause a problem for our low revving street engines. It did cause problems for high revving NASCAR engines when those tiny particles stuck to cylinder walls leading to galling and catastrophic engine failures. Not all of them but if you're the lucky one, you'll be looking for answers and prevention.
I don't want to spend the time and money for a "kit" to wash my friggin' air filter and then sit around waiting for it to dry so I can take more time to re-oil it and then have to put grease around it so it will seal properly when I put it back in the housing. I haven't yet been convinced that there's a benefit to it. I prefer to buy a new one, drop it in and simply throw the old one away. But if you like having an oily lint screen for an air filter, by all means!:B

OK?!.............and after all that when dirt flows through a K&N the micro fine dirt will stick to the oiled material in the filter. Or does the dirt steer around the microscopic filter crevises and go right on to the engine?

Sheesh! :S

Well, based on the ISO 5011 filter testing noted twice in this very thread...that about sums it up.

Unless you've got standardized testing that refutes these findings?

Keep one thing in mind, though, when it comes to the filter testing results:
The relatively poor showing for K&N does not mean "K&N directly leads to engine failure."

There is another way to look at the filter issue. And a logical explanation of how they work, or don't work.

The Mississippi River has sometimes been called the "Big Muddy". The Missouri, which runs nearby, has been sometimes called the "Little Muddy".

The reason they are called that is because both rivers hold fine silt in their moving water. And the reason they do that is because of the slow speed of their flow. Whenever the same water becomes a backwater, the silt settles out into a muck, and the water clears up. The similar speed of flow is also why both rivers have the same-sized-particle sandy bottoms; sized that of table salt. The salt-sized particles fall out of suspension because the water flows precisely no faster. If the water was faster, the bottom would tend to gravel, then faster yet finally, the coarse rock seen so common in mountain streams.

Air is a fluid like water. When flowing, it always carrys fine particles with it. Where I live, the wind blows a lot; ND is second only to Texas in windpower. The air may look clean, but it is not. On severely windy days the haze of larger particles can be seen. Not as much as it used to be before no-till farming, but still there. Enough so that continuously exposed windshields eventually cloud over from the abrasion, and paint loses it's shine.

So if wind "flows" brisk in an intake, why would it deposit sand on the walls. It would deposit sand if the particles were larger than the flow could suspend, but the intake air flows faster than the outside air whence it came. So only a certain type particles would remain in an intake. They would have to be sticky. Sticky, sharp crystaline particles like gypsum or salt dust. White. If there were a low count supply of such "sticky" particles in the outside air, no sign of the pounds of passing dust would be seen riding in the pounds of air an engine inhales.

With an open, non-filtered, intake, even on pavement, the dirt would merely enter the engine, grind a little precisely machined metal away and leave. Whoever I sold my truck to, would pay the price of reduced engine life. I have wind and salt where I live so I would likely see signs of dirt in my intake. Some owners in other parts of the country would remain blissfully unaware, and maybe even suffer less damage from slightly cleaner air.

So why would anyone want to run an air filter with crude open porosity like a K&N instead of a fine-micron paper filter? It seems illogical to me. We all know that the new diesels demand clean, fine-micron fuel filters and no-one argues the point. So is it ok to wear out pistons and bearings, but not injectors?
