2.7 EcoBoost Turbo Whistle and Flutter with Injen Intake

Intake: https://www.americantrucks.com/injen-f150-power-flow-cold-air-intake-pf9015wb-a.html

The intake really improves throttle response

You can hear it a lot more in the cab in person, the camera does not do justice as to how loud it actually is. This intake really helps make a lot more spooling noise and you can even hear some blow off and flutter with it
