MFI high butterfly "split air horns" ?

Hi,
I searched and found few options for air filters on MFI high butterfly. I'm wondering if someone know a source for these split air horns ?

Or you have a set and you can help me with some measurements ?

Thanks and Best Regards

Those were sold here in the late 80 by Race Force. The tin uppers cracked and broke in pieces from vibration. Intermediate pieces were short, too short for my needs, so I made longer pieces and later got carbon upper bells. They have low mass so don’t crack.

Race Force! Remember it well. Another neat Porsche store in Emeryville...now long gone.

Hello
There is a nice period correct solution available from germany : https://www.mittelmotor.de/racing/de/

These guys offer a perfect copy of the airfilter box used in the porsche rally car 911SC/RS

Made my own version. Not period correct but works great.Attachment 532496

Now THAT is funny!!

Tech 9 makes an ITG filter system that attaches to the stock high butterfly air horns. I saw these on their website a long time ago, lost the link, and then saw them on one of Gib's (letsrollbabe) cars. I reached out to Gib and he gave me the contact for Phil at Tech 9 who hooked me up with a set last year. Pm me if you'd like me to forward Phil's contact to you. The first picture below isn't from Tech 9 but it looks like their air filter.

I can also vouch for these on my HBs.
