Top-side air duct set compatible with Arai VX‑Pro4 helmets
Designed as a direct-fit replacement or upgrade to restore and enhance helmet ventilation, these top-side ducts improve airflow, reduce interior heat buildup, and support aerodynamic performance for everyday riding and track use.

Precision-molded for an OEM-style fit, the ducts offer straightforward installation and reliable retention. Engineered materials resist road wear and maintain shape under high-speed conditions, while the airflow profile helps channel fresh air into the helmet and evacuate warm, moist air for clearer comfort and better concentration. Ideal for riders seeking improved ventilation, a snug factory fit, and durable, race-inspired functionality.
