I just traded in my 2014 ST for a 2016. I was about to put my FSWERKS intake in and realized, well shit this isn't going to work. Apparently the 2016 ST's have 2 intake tubes instead of 1. I contacted FSWERKS and they said they need to get a certain number of requests before they can make an adapter for it. I found this post that includes pictures of the change. Mishimoto sells an intake that comes with the adapter, but I have contacted them and they do not sell the adapter separately. Has anyone found any solutions for this?
