ES K&N CAI Air Sucking Sound

I have a 2018 ES and I recently installed a K&N CAI on it. I love the power and the added responsiveness. I wanted to see if anyone else has one of those intakes and experienced an air sucking sound from 2-4K RPM. I checked all of the fittings multiple times for a vacuum leak and I don't hear one. It doesn't happen when idling, just accelerating. The air sucking sound is pretty loud and stops as soon as I let off of the gas. Is this normal for one of these intakes?

Intakes suck in air. Now it's not contained in a box where you don't hear it.
