The Improved Racing CCR catch can I run now in with the recirculating adapter came with set up with a filtered vent, equipped with a fine sponge as a vent filter and came with a spare. The Radium Auto cans I was looking at also had VTA cans as well. They have two different steel mesh style filtering media in them... The CCR VTA is meant to be mounted under the hood as the sponge would get wet during inclement weather. Same with the Radium Auto VTA I'd assume. I always wondered how the SPE external catch can works. There has to be a vent in it.

Edit: I just watched the video bk1992 posted which was very informative. Looks like the 23+ CCV box is a good option too. Great first post @bk1992 and welcome to the forum

Thanks! I saw the SPE video last week going over the 23+ new style, and was sold on the SPE recirculating kit too. After watching this I think I'm going to stick with 23+ style. FYI for anyone out there with late build 22s, I have an 8/22 build and it came with 23+ filter.

The other thing to consider is that the SPE box doesn't have a CDR valve, but the CCV on my 2020 doesn't either 
Guess the screen in the SPE or the filter in the 2020 CCV prevents too much vacuum?

So, I first ran the Mishimoto oil catch can which has adapters under the OEM CCV box. It has a block off plate adapter so to speak, at the front port, and has the rear adapter with two hose fittings to intercept the blowby, send it to the catch can, filter it and then return it to the same adapter. I am now running the bigger and better designed Improved Racing CCR can. So essentially the filtered blow by runs through the box to the intake. I'm just wondering if I would get better flow through the box, with less pressure as a benefit, with the latest factory CCV box design that SPE pop pooed...

Or I get one of those boxes like you have. with the lid/screws, with nothing inside. I'll research this more before doing anything. I just want a box with more flow through it as I'm already filtering the blowby with catch can.

Nah you don't want one like mine. Apparently there is a non-serviceable filter in the rear part of the box and it's small. I'm looking to replace with a 23+ style box or the SPE box.
