I just installed a Mishimoto oil catch can on my 2018 today, it wasn't hard took all of about 45 minutes and I had to stop several times to watch the youtube video install video from Mishimoto. Not all of them attach the same way. The Mishimoto ones comes with all the hardware you'll need except for some teflon tape. here are pictures of the finished product. I paid right at $200 for the Mishimoto one but the name alone is worth the extra bucks along with the finished factory look.
