I threw out a whole AFE intake for my 03. I went to the upgraded stock air filter which I felt was better than the AFE. I don't have dyno numbers or anything to verify this but there was less restriction showing on the indicator and it seemed to pull better. The only thing I lost by going back to stock was turbo whine. I just got a new 2012 and I really like the quiet. As of now I do not plan any modifications. I did a lot of mods on the 03 and for the most part the biggest gains were in some other persons pocket. For my 2 cents worth I say it is a waste but I'm sure I'll be contradicted.

yeah i dont really want to modify at all but im in my truck all day and the mpg is bothering me. otherwise its an amazing truck. i am looking at updating to 1ton springs/leafs, i hate the squating

It'll help the economy if you buy one and certainly help your self esteem. But this engine doesn't have any soft spots (other than dpf and egr madness) that I can tell. GO for it and let us know how it works. need a signature for your truck too!

 

[bigsilver67]

i may try it. thinkin about guttin the dpf too. not sure just dont want to do too many mods. just made a signature, thanks!

That paper filter will pull close to 900 cfm so on a stocker it's no problem plus the filtering is better than the oil type. Save your money

the stock is the best there is. get a psm kit for the stock box. you must do all of the delets and get a smarty jr to get mpg. also get a crank case vent relocation kit

It's a pure waste of your money. The filter won't filter or protect your engine as well as stock and will do absolutely nothing for performance, fuel economy, or your sexual prowess.

What Harvey said. Until you're pushing more than 500 horses, the stock intake is the best.

Another vote for stock air filtration.



Anything else is as useless as the Viagra and Russian Mail Order Bride e-mails that fill my Spam Inbox everyday.

The five posts above me are dead on. The only thing you gain from a CAI is a lighter wallet and being powerstroke "wanna be" with the turbo noise. Use that money towards the deletes.

ok, so what about when you get above 500hp?

Then you need to think about something that will flow more air. Somewhere out there there is a formula for calculating how much air your engine will pump through.
