Airflow Tuning Guide for Air Bar Stark 4
Published 2026 · VapeWholesaleHub trade desk
Airflow tuning is the single adjustment that changes how Stark 4 feels in daily use.
Between the factory gate and the retail shelf, airflow tuning is where most of the value on the Stark 4 is either created or lost.
Seasonality interacts with airflow tuning more than most forecasts allow for, so a rolling review beats an annual one.
Why airflow tuning matters on the Stark 4
Restricted airflow suits mouth to lung customers moving from traditional products.
Retail staff rarely ask about airflow tuning directly, but their questions almost always lead back to it.
Open airflow serves direct lung users who prioritise vapour volume.
