Intake mods....
Pretty much have endless options. U could buy a air intake such as k&n or air raid, or make your own for less money.... all depending on what ur looking for. Does your truck have a mass air flow sensor or is it speed density?
I could argue that oneS sean. Yes you'll take in heated air....less dense air, less fuel needed for combustion. Leaner fuel burn. Less hp, but slightly better mileage. However, on the 5.8, your probably not concerned with mileage. For more power you want a cold air intake and the stock box with a k&n is great. However, given the surface area of two k&n round filters or a single k&n rf1012, the increase in air flow on my 4.9 was a power boost. Just my 2 cents.

just get the flat filter that replaces the stock one, keep everything else. my dodge and 250 already came with the filters so i dont know of any improvements over stock. but my f150 i noticed a lil better MPG and seemed to breath a lil easier.

here is what i did to the intake on my 88 351
....i need a new filter though haha, what i did was disconnect the snorkel, flip the box, and cut off the bottom/top
.......it is not a cold air intake...but it is higher flowing than stock

I was watching an engine show and they were discussing air intakes. So to bring up an old topic again. The designer was saying that the advantage of the cold dense charge was a more efficient burn. Meaning that the existing mixture burns more completely creating more power and less waste material. The ecu will still maintain the same air/fuel ratio therefore still using the same amount of fuel per cycle. So using our more power = less foot on the throttle = more mpg theory, you should do well with a cold air induction. Didn't want to restart an argument and anyone not up with this discussion that's interested can pull up long posts on both sides of the topic. I just thought I'd throw out some new insight. I'll see if I can find a link to the video.
