They add nothing except usually dirtier air. Best flowing and filtering system is the Tymar. next is the AIS ford system. You can also do a DYI with the correct parts. We carry the Tymar, PM if we can help.
The problem with heat shields and routing air through intake boxes is that whenever you direct air flow, you increase restriction. Low restriction is the goal, so using a filter that has the ability to flow large masses of air and then enclosing it in a box yields very poor results. Heat shields do literally nothing. Air flow under the hood is dynamic and not static. It is moving all the time. Hot air will move right around a heat shield at the same temperature and be ingested and the only thing you have caused is turbulence.

You are not going to gain hp or mph by changing the intake alone, because the stock intake is adequate for the stock engine. However, if you make other mods to increase the hp, then you will need either the Tymar, Ford AIS, or Banks intake to supply the extra air that will be needed.

for me K&N COLD AIR INTAKE 99-03 FORD POWERSTROKE DIESEL 7.3L is the best!!!
K&N is the WORST thing you can put on a diesel. I've seen an intake tube on a 7.3 that hadn't done the CCV mod (so it was oily inside) and it looked like a clogged artery.
Airflow inside an intake box is constant, so really doesn't have time to heat up from the engine bay. I believe the CFM demand for a stock 7.3 SD is 466 CFM (or maybe ^3 inches). Then it goes up from there with tuning. If you have an open intake, then you are sucking in really hot air from the engine bay. The intake box is sealed against the hood. I have seen some people do a diy 6637 intake with a fabricated box around it.
And adding the zoodad mod will make it more of a force fed intake.
AFE, AIS, Air Raid, Volant, S&B....any of those IMO.

DIY/Tymar with the waterproof Donaldson or the AIS for me. I have both and they are great, the AIS is nice and quiet but still flows well enough for my stock application and filters excellent, as does the DIY open element. The open element intake systems will generate quite a bit of turbo noise, but the flow and filtration tends to be excellent as well. I did not notice any performance differences between my DIY and the AIS I am currently running.
