Cub Crafters has a similar product. I put one in my O-340. It helped some with those issues but it’s nothing like fuel injection.

There is a SB 258 out for that. It is used for sump/carb mismatch .https://www.shortwingpipers.org/forum/showthread.php?6247-Service-Bulletin-258 Post #5 has a good copy of the SB. Not really a extra power mod, more like fixing a issue that was decreasing power you should of had to begin with.

One of my O-320's had that cone. It fell out when we tore it down for overhaul. I think it was put back in later. The talk said leave it out for better flow, but I see from the SB why not to. We did flow the intake riser to induction tube junctions some with a Dremel. There was rough casting in that area...just made it smoother and same shape/diameter.

Is this cone related / relevant to the -12 and -32 carb discussion I posted about a few weeks back?

It is all in the O-320 Type Certificate.

Yes. Multiple threads here and on the shortwing site about this.
