Here's what I could find for stock manifolds if yours is too banged up and this "lean" thing is something to be afraid of. I still haven't seen any facts behind this, nor has anyone described the symptoms of making your truck run lean.
Stock Intake Manifold: http://cgi.ebay.com/ebaymotors/CAR-C...Q5fAccessories
Stock Filter Replacement: http://cgi.ebay.com/ebaymotors/K-N-O...Q5fAccessories
I am considering cleaning out my old intake and purchasing a new filter as it looks like S***- if this lean thing is truely an issue for people without programmers.

Great info / debate. I've been on the fence for quite some time due to the fact that I won't be able to purchase both a programmer and CAI in a close time frame. Money is tight enough. And yes, I know of the gotts mod but I don't truly trust that and/or making it perfect. I'm in the same boat as a lot owners here. Is it really worth the $$ to purchase an aftermarket product just to turn around and spend more on fixing what it damaged?
I guess in the end, I can just order one product, store it and wait til I can purchase the second item to avoid all of this.

I deleted the custom tune because it was for no cats/O2 sensors. I talked with the guy who did the custom tune, he said to do this because the original owner did not sell me the actual programmer/tool, and if he was going to install another tune he'd need to charge me more money. Since I don't work the truck hard, and try to keep it under 2500 RPM, he said a performance to is not worth the $600 tool + $700 custom tune/dyno vrs the $70 dealer PCM reflash charge. But now I'm back to this whole "lean" issue.
I heard some timing chains rub on the cover and wear out the guides quickly, resulting in a big $$$ dealer fix.
