Mountune 2016 Focus RS Uprated Air Recirculation Valve
Product Review (submitted on December 30, 2016):
Installed this on my 2016 Focus RS when I started having boost bleeding issues. If you remove the stock plastic valve, you'll instantly see the superior quality of the Mountune vs. Stock. It uses a piston style valve vs. the stock crappy spring. If you are looking for loud turbo noises, this isn't for you. It's a huge step up from stock and my boost issues are gone. The best part is Mountune's products DO NOT void the Ford factory warranty.
