Very easy to install
Very fast shipping. The part is made extremely well and the installation was easy. The sound of the extra air to the engine and the additional hp and torque was felt immediately. When i test drove it, my wife said she could hear me while sitting on the porch. Made a big difference.

My aftermarket bov sounded better on its own before installing this intake
Took me 30 minutes to install with professional help. It's giving flutter at low and high Rpms. My aftermarket bov sounded better on its own before installing this intake. The flutter dump takes away that sweet blow off sound. I made sure everything was installed right. Also, I don't like how I feel constant air when i press the gas as in before I only felt and heard my magnaflow exhaust. It makes it feel like it's quieter from the inside of the car.

I put this on my ecoboost Mustang and it works great! It does not sound like a 4cyl when you get on it. I already had a custom exhaust, tuner and blow-off valve on it. I highly recommend this intake for the ecoboost. I know need to sned in for a new tune for the intake.

Just put this on my 2016 Eco last week, definite increase in HP, torque and MPG. Took about 1 hour to but on, more than worth the effort, now on to exhaust to get the air out more efficiently.
