That was my exact question to the folks at Dave Smith in kellogg, the reply was that a K&N would void my warrenty...
I drove it home today and if i ever needed more power then I best own a tank retriever, that thing is a monster...pulled 4th of July at 75 and never shifted a gear.... AWESOME.
The reason of the first question was in regards to the comments about more air in , more air out is good for the eng...
I guess lots of research is in the offing, but I for sure ain't gonna be dumping thousands of $$$ to make it go faster or growl louder!!
I would add that if your in the market for a new truck of any kind call Dave Smith , With one phone call they beat Lithia by 1000 bucks and that after a week and a half of haggling with Lithia...
Good ppl to deal with...NO BS !! they say their rig is this much and what's your trade... I liked the whole experince..very professional...

NO. Because they do not build motors to be optimized for performance. They build them to be most compliant with federal guidelines and efficiency and most of all cost effective. If they came out in optimum shape there wouldn't be companies like SuperChips, BullyDog, Edge, K&N, Mobil 1, etc. Because every vehicle would come with the best on it.
Look at the top end cars, Vipers/Vettes/GT's, and they often times come with things they aren't going to put on a mid-range car.
Not in my rig. There was an exhaustive scientific test done on the K&N and the test results do not support the marketing campaign. I installed a newer Ford 6.0 ltr. air filtration system on my truck. This is the same system that is installed on the M1 Abrams tanks in Iraq. I've also got a a neighbor who is a Ford Heavy truck manager and attests to the amount of denied warranty claims on Powerstroke diesels from aftermarket air filters. Not worth taking a chance on. Small particles that get pass the filter will eat your engine alive (BIG $).

I run one on my truck in the summer (after the spring dust is swept off the streets here in the north) for towing season. I have taken the air intake tube off after running the K&N and found dust in it after the filter. I believe they flow more air (I can hear the turbo more with the K&N), but they do not filter as well IMO.
Of all the snake oil products out there making magic claims the air filter market has to be the worst. On most vehicles there's simply not any performance gains to be had by going to different air filter, the stock filter flows far more air than the engine can use already. Without some large performance modifications to your engine you don't need more airflow, you've got plenty already. Take the stock filter out of your truck and look at it, it's huge and has a lot of deep pleats with a bunch of surface area, it's not a restriction. There is absolutely no benefit to be had by switching to a K&N filter, but there's a lot of risk due to the poor filtration properties. I for one would never put a K&N filter on any vehicle. If, for some reason, I did install a heavily modified engine in one of my vehicles and needed the extra airflow then I would go with a filter from a more reputable company than K&N.
Well, everybody has there own ideas on this. I have used K&N filters for years, on many different vehicles. When installed properly, they work fine. I have had one in my 2001 Dodge since the first week I owned it. Increased air flow helps bring down exhaust temps,verified by a gauge. As for more dirt, see a copy of my oil analysis, done at 20,000 miles and again at 40,000 miles. Look at the silicone line, this is where dirt/dust getting past a filter will show up. Universal averages from the oil lab show a silicone average of 8ppm, based on other like vehicles, most of them having paper filters. Both of my tests showed silicone number below that(6ppm and 4ppm).
So, based on science and chemistry, for me, the K&N filter works just fine. At my next oil change @75,000 miles, I will send in another sample and it should show the same results.

Yup, when installed properly they do work fine. But there is no known benefit to them, so what is the point?
And if you don't install it correctly it will let a lot of dirt in.
And because it is an oil filter it needs to be cleaned from time to time. And if you don't clean it as often as you should it gets to be more restrictive then the stock filter.
And if you over oil it and can foul up your MAF and cause some interesting side effects.
Or you can just get the stock air filter and drop it in.

If you do use a K&N, or other oiled filter watch out for the oil build up on the MAP sensor. Also make sure to clean it as schedualed. I think there is more to be lost than gained by running one though.
WOW, I wonder if the people over at some of the Dodge sites know about all of you experts over here!! You guys simply amaze me. Putting a K&N filter, or any aftermarket filter that meets the filtering specs of the OEM filter will not void your warranty. That is exactly what the Magnusson Moss Act protects us from. Too bad it can't protect us from internet experts who had a friend of a friends uncle who blew up his engine by putting on a K&N filter. And for all of you that believe that the manufacturer of your vehicle only puts the best equipment on your vehicle from the factory, please tell me that you are not serious. If the manufacturer of any vehicle can save a quarter on any component that they put into a new vehicle, they will jump on it. All that part has to do is make it through the warranty period. They call misinformed people Sheeples. Because someone has seriously pulled the wool over your eyes. The key to getting any aftermarket product to work correctly is to ensure that it is correctly installed. And to the poster that stated in order to get in more air, they had to make bigger holes, did you ever hear of more surface area?? Some statements really do reinforce the fact that some people really should not speak about things that they have no first hand knowledge about.
