Swoosh thud is a good description.
Its the intake sucking up a bunch of air, then you abruptly letting off the throttle so the pressure changes drastically and has to go somewhere.
The CAI inc cai is a sealed box, so itll make this sound more dramatic than the K&N because of even less of a place for the pressure to go.
I get the exact same noise when shutting my car off, everytime. I dont hear it when im driving really, but I have headers and loud exhaust.
Next time you turn the car off, roll the window down and listen for it, if its the same noise you hear when you drive, then its normal!
