The Pop-it will fit any 2-3/16" (56mm) filler necks.
Based on the limited testing I was able to do, this 2016 Stant document can be used for a general, but incomplete, reference.
I was able to confirm part numbers #12422, #12423, and #12410 have compatible filer necks.
Using Ctrl-F, and entering the part numbers 12422, 12423, and 12410 this accounts for 53% of all cars on that list. BMW/Mini that use the larger GLD036 make up 10% of the remaining vehicles.
Without more available vehicles to test I cannot confirm or rule out the remaining part numbers at this time.
Hope that helps.
