Airflow tuning is the single adjustment that changes how Royal 4 feels in daily use.
Every serious sourcing conversation about the Royal 4 eventually arrives at airflow tuning, usually because it is where cost and risk meet.
Retail staff rarely ask about airflow tuning directly, but their questions almost always lead back to it.
Why airflow tuning matters on the Royal 4
Restricted airflow suits mouth to lung customers moving from traditional products.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Royal 4.
