K&N air filiters

[PTsideshow]

While fueling the ram at a local place I ran into a legend in his own mind diesel type telling me that I must get one of the K&N air filters for the turbo on the ram. Know I know enough that all the hype in their commercials is designed mostly to make more for the companies from the sticker from the auto parts guys.
My questions are does it do anything to improve mileage and or performance? And are they worth the money?

Stand back when the posts start coming in. In the meantime do a search on this forum as well as 3rd gen. They'll be several hrs of reading.

Very controversial(sp?) topic. When you get a chance go to the search forum and see what you come up with. It allows a lot of dirt in along with the air. Some describe it as a window screen. It'll dust out and kill your engine. If you install one on a vehicle under warranty, and bring it in for service the dealer will make a note of it and you can kiss your warranty good bye. There are a few die hard fans who swear by them, and that's fine. I'm not posting to start a war. Everyone is free to do as they please.

Even though you didn't ask, as far as filters go I would stick with Fleetguard. They are the filter division of Cummins. Who would know better about filtration than the folks who built your Cummins?

Well said.

When we bought our 2001.5 the Dodge dealer sold me one. Within a year or so, Chrysler put out a service bulletin against them and I removed mine. Snoking

Well that answers my question, I knew there had to be a down side and that is a big one warrenty killer. Snice I don't intend to either major off road or race it. I will stick with the stock filter.
thanks for the responses.

Buy Mopar/Fleetguard and Racor products for your RAM, it will be happy!

SNOKING, happy now?

My dealer noticed mine and told me they're supposed to let Cummins know when they find one on your vehicle. Cummins then will void your warranty apparently. They're only good for stopping sticks and bricks according to Cummins. I removed mine and replaced it with a stock filter after hearing that.

Your dealer is blowing smoke up your backside........FCA/Ram provides the warranty on the engine as they buy it from Cummins with no warranty.........

[TFucili]

They are correct about the "sticks and bricks", though

I used an AFE filter on my 2002 with no problems.

Same here......I used one in my 2001 for 13+ years and oil tests always came back great.....

Oiled or drop in replacement?

Some will say the oiled filters are sticky enough to grab particles out of the air. But i did have a K & N on a mitsubishi, and was concerned about the visible size of the holes. So i decided against such

If this is for me......I had a couple of different setups over the years. Stock paper, Ran a Scotty 2 for a number of years, using a K&N oiled filter, seemed to help with EGT, but was a bit noisy in the cab. Got tired of the noise, went to a K&N drop in. Oil tests always came back great, the worst silicone(dirt) number of all the test was a 4........pretty good in my book.

[jhenderson]

Yes, it was for you and you pretty much summed it up. I believe the oiled filters are a much poorer choice for long term use. Particularly without constant attention. I've never seen a k+n drop in but the afe looked pretty good to me.

Great info and I think that will answer my question to stick with the factory filter and just change it more often
