Just make sure you get the longer caps for the Model X. The Model 3/Y/S ones are shorter and may fall off as they don’t grip over as much lug nut. Pics below to show the 3/Y, S, and X lengths of caps. The ones you can buy off Amazon or Ebay are usually shorter ones, so I’d suggest getting them from a Tesla service center and they were less than $20 for a set when I purchased mine a few years back.
