Arai Frost Black Diffuser Type 12 Genuine Helmet Vent Replacement

About this Arai Arai Frost Black Diffuser Type 12 Genuine Helmet Vent Replacement

Restore the flagship aerodynamic stability and elite cooling performance of your premium racing helmet with the genuine Arai Diffuser Type 10 Helmet Vent Replacement. Engineered to meet Arai's uncompromising track and road safety standards, this factory-original replacement part is designed to maintain high-speed stability and structural integrity. The Type 12 Diffuser setup is fully compatible with premium models like the Arai RX-7V, RX-7V Evo, SZ-R VAS, and SZ-Ram X.

Precision-molded from a high-impact, lightweight polycarbonate composite, this Type 12 unit is engineered 20mm longer than previous generations, increasing airflow efficiency by an impressive 19 percent to rapidly pull heat and moisture through the internal EPS channels. Crucially, the diffuser is designed to break away cleanly from the outer shell during an impact, preserving Arai's core "Glancing Off" safety philosophy by preventing the helmet from catching on obstacles during an accident.

The replacement diffuser features an updated air intake vent switch with a three-position sliding shutter mechanism (open, half-open, and closed). When fully closed, it forms a tight, weatherproof barrier that significantly minimizes road noise and prevents water intrusion during damp rides. Over time, track debris, high-speed stone chips, or accidental drops can chip, scratch, or degrade your original vents. Replacing them with this factory-fresh, genuine component restores optimal aerodynamic efficiency and eliminates high-speed buffeting. Each diffuser arrives brand new and ready for a straightforward installation using a clean, tool-free adhesive application process.
