I have a 2004 4.7 and am looking for feedback on cold air intake, should I go with K&N or is there another brand that is better? If so which one and who has the best prices online for the system.

 

You have a PM.

 

K&N FIPK system was the best $$ i ever spent on my truck

 

I went with the Aircharger instead of the FIPK.
The best online price I could find was at http://www.4filters.com/

Around town my mpg went up from about 14 to about 16, can't say about the highway though but I would expect a simliar increase.

 

Basically, every kit will be the same, but I'd go with K&N anyway.

 

Ok I looked at all the ones offered and I have ordered the Airaid system.

Will let you know how good it works for me

 

this is what i did to my dakota w/ 4.7, just go down to autozone and but one 90* elbow and a 4" extension(spectre products) and buy any air filter w/ a 3" inlet and you have an intake

 

I did see your air intake mod Kikoy only thing is I really want "Cold Air" the way you made yours it is going to be sucking in all the super hot air strait off the radiator.
Also I need it to be "Legal" in California ie EPA certified.

 

If you don't want to spend a lot of $$$ then I would suggest just buying a K&N drop-in filter. They only cost about 40-50 bucks. You could always buy the whole system later on if you wanted.

I had a K&N drop in my 2003 Dodge Dakota truck before I traded it in on this one it was decent but I am gonna try the Airaid system and I will let you guys know how it goes
