Customer Reviews
Hi, it says 2015-2020 STI on site but when I got the intake it says 2015-17 STI, anyways quality of the parts are absolutely perfect imo in terms of finish and feel. I realized the 15-17 STI intake system is a bit longer so the fender Liner allows space for it to fit. But in the 18-20 it's slightly shorter. So I ran into and issue where the intake was hitting the fender liner, I had to buy a different intake end which was shorter in order to fit my fender liner on. Also the heat shield needed to be slightly bend and also cut in order to sit flush. The end product looks well. Just wouldn't be for someone without extra tools. Like cutting and such. I love the intake and my car feels faster definitely. FOR THE PRICE COMPARED TO OTHER INTAKES ITS WORTH, BUT 18-20 STI INTAKE SYTEM IS SLIGHTLY DIFFERENT THAN 2015-17 SUBIE SUPPLY SHOULD CHANGE IT.
