I installed my K&N air filter this morning. I wasn't expecting much, and I was happily surprised. I had a couple of office mates listen to the exhaust before and after I installed it. We all agreed it was definitely throatier After.....

Then I took it for a ride. She had Noticeably more power, in every gear, in every range..... I'm very impressed that such a relatively cheap and easy mod can enhance performance as much as it did..... Wonder how she'll perform when I add an exhaust??

No idea about the increased mpg claim yet, and I'm not going to adhere to the 40K between cleanings claimed by K&N, but so what? I'll be cleaning it, instead of replacing it!!

Tim,

Was this the K&N drop in filter or the K&N cold air intake? I'm about to get either one and I'd like to know which I should go with on my 04 Hemi

Gravymonkey...... It was just the drop-in air filter. Disconnected the flex hose, undid the clips on the air box, and slipped her in. Total Price.... $58 plus taxes..... I like it......

 

Although..... I wouldn't counsel you against going with the cold air kit, especially if you're going to make changes to increase the exhaust.

I've also read and heard that the HEMI doesn't respond as significantly to the cold air intake mod, given the computerized sophistication of the engine. I have no way of knowing it that's accurate......

I just know it made a real difference in performance on my 4.7..... Hope that helps.....

 

I just bought a K&N filter and I paid $65 for it. I put it in yesterday and today(in the 20 miles I drove) I noticed a .5 mpg increase. I am sure the more I drive it the more I will see an increase.

But the truth is, why pay $30 for a new filter every time when you can pay $65 once and get better performance/mpg and never have to buy another one? Yah it's well worth it. Even at .5 mpg increase, it will eventually pay for itself. You can't say that of regular filters. In fact, they are COSTING you money and performance

 

Ram04 is right about increased silica when using the K&N filters.

You may think the increased air flow is giving you a power boost, but your not thinking about the increased engine wear that your getting from the silica.

For those that claim to get .5 mpg to even better with a drop-in filter, i'm willing to bet that a good part of the increase is due to you using less gas pedal as you monitor your new filters affect on mileage.

On my Dakota, I have used a homebrew CAI and did notice increased acceleration, and more noise coming from the intake. I removed it because it became soiled with dirt and bugs within 3 months of installing it. I switched to a K&N drop-in in my and then went back and forth with a paper filter. I noticed no difference between the paper filter and the K&N drop-in.

I'm getting rid of the K&N drop-in in my Dakota and goind with a Flowzair oiled foam filter from Amsoil. They work on the same concept as a dirt bike air filter does. Here si a link to them if your interested. http://www.amsoil.com/products/ts.html Their ability to trap dirt is even better than K&N's.

 

sgbofav..... I'm just reporting my experience. If silica is an issue, it's the first I've heard of it... I'd like to hear more, if there is more....

I'm interested in making my 4.7 work better, and for a very long time.....

Best wishes..... Tim

 

I did not intend to discount your experience with the drop-in filter. I was more interested in prolonging your engine.

I just found this today. Owner was using a K&N drop-in but removed it after receiving the oil analysis report. http://elabfcsvrt.fdu.edu/bartsch/Pr...00%20Miles.jpg


For all those members that swear by K&N, this link will be an eye opener for you. http://theoildrop.server101.com/ubb/...;f=15;t=000175

Bill,

 

Bill..... I read your attached websites, and if you're an Amsoil distributor, good luck with it.

I pulled my 20' boat up the Maryhill grade this afternoon and I clearly had more power since installing the K&N filter, and I know that's just one man's opinon. I run Mobil 1, and I'll be changing it more often than recommended (at least for a few changes) to make sure everything is OK.

All I can tell you is, my truck runs better, with noticeably more power after making this one and only performance Mod. Regards, Tim

 

Tim,

I think your misjudging my intentions.

I was not trying to sell Amsoil or their products, I was showing others viable options in lieu of K&N . You mentioned that you wanted to make your truck last a long time. This was my reasoning for linking to websites showing K&N's weakness which is increased silica or sand particulates. I stopped using them becuase of this information.

I shared my personal experience with K&N and gains or lack thereof because I didn't want some of the impressionable youngsters to think K&Ns are the greatest invention since the wheel. It may have worked for you, but the drop in did not help for me. The cone filter on my CAI did make a big difference both noise and power but it gets dirty too fast where I live.

If you want to make your truck last a long time, you should change your gear-lube to synthetic, keep running synthetic oil, you may even consider a good ATF+4 synthetic ATF. Check out Kale (SyntheticMan's) bypass system also.


I sponsor two other websites for Amsoil, Dodgetalk and Pavementsucks
I'll let Kale do the selling here.


Bill,

Here is my CAI's on both trucks. The Ram has an S&B pro flow filter and the Dakota's is a K&N. I removed the Dakotas for several reasons. I plan on installing an oil bypass filtration system and I don't want any other abrasive "stuff" entering the engine.
