Your restrictive airbox silences most of the spool noise you would normally hear. If you have an open filter or a cone filter + MAF adapter you'll hear it.

If I listen I can hear mine (BOV too) & I'm stock except for a K&N OEM type drop in air filter.

MAF = Mass Airflow Sensor

Open element filter, MAF, and hard intake pipe:

The thing was super silent with the factory pieces. After a K&N to replace the airbox and Dejon pipe to replace the factory intake (seriously look inside that thing) you could hear all sorts of fun noises.

Open filter kit: STM: K&N FILTER AND MAS ADAPTER | 2G DSM 95-99 | EVO VIII-IX | 91-99 3000GT

Once the filter box is removed and replaced with a cone it will make a lot more noise.
