what is that extra piece on the soup bowl for ????
and I seriously doubt you can gain any extra horsepower by removing the soup bowl, but you can sure make it louder.....
think the OEM style is just to direct airflow in a uniform manner and you ain't getting more air into the engine if you remove it, the 93 has a Ram air scoop in the front to begin with too, and unless you change things with the amount of fuel injected I doubt you will gain any Horsepower. JMHO

From what I understand, it will probably lose a little power cutting it off, somehow disrupts velocity of the air and how it draws.
But do it if you want to, I think what it really does is quiet the injector noise from the intake, that's pretty much it.
But > that is a huge soup bowl..
Should run nearly silent > like a ninja.

If you can find a 6.9 lid it doesn't have that cone, it had a reducer in the bottom which I removed because its a choke point. Didn't notice any difference from before noise wise, which may be why they changed the design to yours

So, does this alien spaceship futuristic 'soup bowl' offer any airflow benefit over the 6.9 style? Enough to bother picking one up from the boneyard if I see one?

One thing I can say for sure is that an engineer designed that on the lid for a reason and Ford/International decided that it was worth the extra cost to include it in production. I doubt highly that it relates to any emission control, more likely an NVH concern, but that may be unlikely as well. The one tuck I had where that had been removed was noticeably louder with intake noise, especially once a valve got sticky. I'd just leave well enough alone TBH, and that tube tacked to the bottom is on my 1993 as well. It goes up to the cavity that the ether nozzle is in. I would imagine that the chamber as a resonator as I am sure you've heard the intake growl revving the engine with the air cleaner off.

Working with engineers, especially those who are hobbyists and understand hands on, has taught me a lot about systems and the amount of work, consideration, and failure that goes into a finished product. There is still a lot of Bubba science in the automotive community, especially around these older vehicles. It's almost as if some people believe the laws of nature were different or didn't exist in the past. This ain't, and wasn't, cutting edge rocket surgery.

Well said, 119ER, we'd have factory engineers, factory reps from everywhere from Cummins, Detroit Diesel to Locktite/Permatex reps come to truck shops I've worked in to give a yearly school and it's amazing the inside info those guys have access to and share since they've got nation/world wide data coming in to them constantly. Not to mention their hands on factory engines, transmissions, etc, in test stands and all. Love it when a "keyboard mechanic" feels obligated to inform others those factory boys don't have a clue.
