Vortz Airbox fir Twin HS4s

[Chris Ed]

I have a Vortz airbox for use on my 72 GT running twin HS4 carbs, it is undergoing a full restoration and was wondering if anyone had any experience on which air filters to use, it has trumpets in the housing so I guess foam or circular, as the air intakes are on one side i was thinking a domed foam may be better as circulars may restrict air from the inlet tubes reaching the far carb?

Do you have pictures?

Here’s a snap from the Vortz book of Nick working on a set of carbs.
You can see he used foam around the edge of the box with a foam partition in the middle leaving a square opening around each bell mouth.

I don’t know where you would be able to get the correct type of filter material though?
