Ok, performance upgrade time. Now I've never done a CAI upgrade before, but I do know why I'm upgrading. I just don't know which CAI to purchase as far as best bang for the dollar. Anyone want to chime in? Thanks in advance!:smileup:

AEM

I like the AEM. Had the K&N on my jeep and my H3 and I didnt like that I had to oil the filter, you have to be on the money with the oiling . Too much gets all over too little doesnt work as well. AEM is a dry filter I like it better. As far as performance they are about the same! JMO good luck!

I have the AEM Brute Force CAI for my RT. It's great and no oiling!! :smileup:

Thanks ross! Spot on!

Having not to oil it, and being "on the money with oiling" as rossmore said, is exactly the one thing that sways me from K&N.

Stop by, ill let you take it for a blast! What a differance the cai and cat back make! PM me and ill give you a # and address

 

[NitroBilly]

Ok, no problem! Sounds great! I'm going to be getting a Borla exhaust. Heard so many good things about them.

Drop in K&N and a cat back..save the money. I had a CAI and a drop in on my last truck and noticed no differance in the 2. My nitro with a drop in and a magnaflow is cool and big improvment in the MPG...Just my 2 cents

Note the highly restrictive baffle on the 3.7. For this reason, a drop-in K&N filter will not perform as well as a CAI that removes this baffle.

AEM or K&N probably produce about the same gain. There is no rocket science here. I have installed both and I think the K&N has a little bit better fit and finish than the AEM. I also am partial to the oil-wetted replaceable filter. I've had them for years and they filter well and don't need to be replaced. The oil process is very simple.

Scott, that 2 cents is VERY valuable. I just don't want anything that has to be oiled all the time.

You only need to clean & oil the K&N every 10,000 miles under normal conditions.

Washing the filter takes a bit of time, but you don't need to go out and buy a new filter. Oiling is a 2 minute job at best. The oil comes in a spray can and is dyed red so that you can easily see how much you put on.

If you drive on dusty country roads like I sometimes do, an oiled filter is a better choice as it can easily be cleaned off like new after eating a bunch of dust.

I do agree it is a easy process to oil but....you do have to wash the K&N and wait for it to dry, most times overnight. I have them in all my vehicles and also use them racing, but I do keep my old stock filter around to put in for the drying time. Over oiling is the worst problem on these. All said I wouldn't get ride of my filters for anything, the benifits out way the work.

 

[Surfer88]

I have the 4.0L K&N CAI and i REALLLY felt the power....
It adds 9 HP and about 1 mpg.
Sounds beastly too when you let it hit 4,000 RPM

And for the cleaning, I mean if you want nice stuff you have to take care of it. You go to pep boys and buy the cleaning kit for $15 and take 10 mins out of your day once every 3 months to clean your damn filter. Really not difficult at all. As Ken said it is a red dye so it is hard to mess up.

The K&N also has a fatter, beafier look to it than the AEM. Looks nice when you pop the hood.

Another thing is the K&N is an American made product, which I prefer.

Did I help or ramble too much?

I appreciate everyone comments so far, and want to thank you all again! I do like K&N air filters, I actually had one on a scooter now that I remember (by the way, it made that sucker very fast!), however, I don't like the idea of the oil cleaning , even if it's every 3 months or whatever. With that said, I went and purchased an AEM BF, that I'm sure will look just as good under the hood as a K&N! Thanks again, everyone! BTW, got the AEM brand new off ebay for $170 shipped.:Racing:

 

[fhartell]

i have the AEM w/ a K&N filter because I dont like how AEM's filter is & they didn't have there CAI out yet. After seeing the install I'm glad I went w/ AEM!!!

 

[fcsallan]

K&N=Made in USA

That is all I would need to know.

 

[Pshrynk]

CAI's in a lot of applications won't make much of a difference except to lighten your wallet.

Here's a link to an IMPARTIAL dyno and track test of CAI's done on a Dodge LX body. (Magnums, 300's etc

I am currently in the process of deciding between the K&N or the AEM for my Nitro (3.7L) I have heard that AEM is the company that supplies the Mopar CAI's. And I have also heard the the fit and finish on the Mopar units is much better than the K&N, as well as the AEM now has a oiled filter (blue) just like the K&N. Can anyone conform or deny this. Otherwise I think I will just be going with the AEM as it is cheaper than the K&N (only 10 bucks) but cheaper nonetheless.

I have the AEM Brute Force CAI and the filter I got was white and not the oiled kind. Can't comment on the blue filters.

 

[petey]

I just ordered the 77 series K&N. In my opinion, the oiled filter will work much better than the dry filter from AEM. Plus the red filter matches my red Nitro!!:chuckle::chuckle: I think when choosing it would be consumer preference. They probably are pretty equal in fit, performance, and cost. No use splitting hairs too much. My .02

 

[Waldorf]

I think you are right in your assumptions about performance. I wanted a K&N but at the time (Oct-Nov 2007) they hadn't come out with the 4.0L engine model yet, so I went with the AEM Brute Force.
