1G Oil feed Restrictor application options

Hey guys I’ve got an extremepsi oil filter housing feed kit for my turbo. I want to run a restrictor on there and RTM offers a -4AN 90-Degree Oil Feed Fitting with a built in restrictor...
Will this work on that kit or is it not at -4an?

I have no idea what you're asking here...obviously if they're advertising the kit to fit whatever turbo you're using then I'm sure it'll work. Just be sure the restrictor size is correct for the amount of pressure the turbo needs.
