Across the trade, airflow tuning is the point where good intentions meet operational reality on the Royal 4.

Cash flow is the quiet constraint behind airflow tuning: the cheapest option is rarely the one that frees the most working capital.

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.
