Soup Bowl Mod...

[firemedicmonkey]

Can any one point me to a thread with Pics / Info on the soup bowl mod for the factory air-cleaner lid? I have run a search and am overwelmed with peopel talking about doing it and how it helps with HP and fuel economy... Can't find a how to or before and after pics...


Does it even apply for my truck... '93 F-250 7.3 N/A

Take your air cleaner lid off, there will be a rounded piece of steel affixed to it, cut it off. Done. If there isn't one there, it's already done, or someone switched it for a 6.9 lid. Looks like this:

Thanks...
do you have to cut the whole circumfrence or is it just tacked in spots?

i took a sawzall and cut as close to the lid as i could. then for good measure, i used a grinder and took it down some more. i also drilled some holes in the flap part of the filterhousing base, the part that deflects the incoming air. i didnt notice a whole lot of gain. the trucked smoked less on wot. anything you can do to let more air in the better.

Eh, I just found a lid from a 6.9 engine that didn't have the soup bowl - these trucks have the airflow restricted at the bottom of the air box instead, so lid is nice and flat. Best combination is one of those 6.9 lids, and a 7.3 air box, you get large bottom opening and no soup bowl.

nice... idea!

I would just drill out the spot welds, remove the bowl then weld up the spot weld holes

There's nothin better than cheap (or free) mods that actually work!

The 6.9L had the soup bowl also... I know because i cut mine off.

Some 6.9s have it, some don't - the ones that don't have the soup bowl have instead a very restrictive opening at the bottom of the air box, it's only like 3" in diameter or so. IIRC vans have that setup too, tho I did get my bowl-less 6.9 lid off a truck in the junkyard and not a van.

Interesting, well the only thing i noticed after pulling it off was more noise in the cabin. And if you dont put the hose on it gets even worse. These trucks make a lot of intake noise. At 55mph you can barely have a conversation in the truck with the person next to you.

Isn't that the point of owning one of these trucks! Oh and being able to laugh my ass off when the neighbor gets his brand new rig repo'd and asks me for a ride to work in my POS

The lid I'm using was off of a van with a 7.3 and it had the restrictor plate but no soup bowl.

The restrictor plate is easy to get rid of as well. It's just spot welded in 4 places IIRC. Took all of 10 minutes to get mine out.
