I added the inlet on my 2017 86 and I have to say Holly shit my car is so quiet now lol good thing I have my invidia n1 coming this week. The other thing is that the fit wasn't really good, I feel like on the 2017 to fit the airbox the inlet would have need to be 1 cm longer on the airbox side, I had to king the inlet and the airbox to get it fit, once clamped the airbox is sticking out a little bit and you can see the foam between the airbox and snorkel.
