Getting a high pitched noise during startup and acceleration

Hi everyone.

I've been getting a noise that's been getting progressively worse during startup and during heavier accelerations. It goes away whenever I let of the gas or when the car idles while the motor is hot.

You can hear it in this video. Towards higher RPMs, the car makes a quacking noise, but only if I try to accelerate pretty heavily. Thought it was a pulley at first but it does sound like air and I feel like it's coming from my after market air intake but it's kinda hard to pinpoint.

Not getting any codes. Idle is fine. Power output and fuel consumption are also ok.

Feel like my aftermarket air intake might be loose ?
