Not too bad
While the intake functions well and sounds better and you hear more turbo blowoff than stock on my 2016 Ford Fusion 2.0t ecoboost, it still has a funny sound to it at times. Performs well and installation wasn't too bad. Went fairly smoothly with the exception that the grommet for the air temp sensor did not fit at all. Instructions say to bore out the hole 3/4 inch. Did so and grommet was tight to fit in but managed. Once in the air temp sensor wouldn't fit and had to bore out grommet also.
