Yesh, Zap is an rebuildable atomizer (RBA - shortform) specially design for Provari. If you get a provari you will need to get an atomizer. If will get both the provari and the zap, its gonna burn a big hole of your pocket. I would suggest you do more research before you commit. You will need to learn how to build a coil and wick inorder to use an RBA. Plus you will also need to buy material like Kanthal wire, SS mesh or slica wick etc. to do up the coil. Go read up modders section in the forum, or search for RBA. If u really wanna try an RBA, i would suggest you get a clone one and try to see if you are really into it before committing into something expensive, thats how I learn (recommended by bro here).
