For the mechanically uninclined.
I just wanted to mention to those that aren't mechanics or pretending to be not to be afraid to do some things in their 7.3's. I just did a couple things to mine in the last couple hours. I changed the fuel filter for one. I searched this site. I looked at my Haynes manual. I saw the instructions that came in the box with the filter. I kept thinking to myself, this can't be this easy, can it? Well, it was. I even found a fuel filter wrench when I was looking for something else entirely. Took only a few minutes.
Then, I did the DIY intake. Thanks to all on this forum who put up detailed instructions on doing the mod. Like I read on some threads, it took longer to remove the old air box than to install the new monster filter. Nothing to it if you've got the stuff you need before you begin. I have only had my truck for about 3 months and figured I'd change these filters because I don't know when they were changed last. I don't know how the fuel filter is supposed to look but it didn't look too bad, I don't think. The air filter, however, was brutal. I mean it was plugged. I can only imagine how choked my engine has been. I only took the truck for a short test drive, but I sure noticed the 'whoosh' sound on deceleration. I almost think the truck sounds different at idle, but that could be my imagination. Anyway, just wanted to give props to the guys on the forum willing to help out those of us less talented and experienced.
