Arai GP-J3 Top Duct

The Arai GP-J3 Top Duct is a genuine factory replacement ventilation component engineered specifically for the Arai GP-J3 open-face motorsport helmet. Over an intense racing season, top vents can become clogged with track debris, damaged by impact, or degraded during transport. This official Arai part allows you to restore your helmet's original aerodynamic profile and cooling efficiency without compromising the structural integrity of the shell.

Clean Factory Styling

Designed to integrate seamlessly into the helmet’s classic open-face lines, this replacement duct ensures that fresh air is properly drawn into the internal cooling channels. To help you maintain a uniform look with your team livery or standard factory paintwork, the duct is available in two classic options:

• Black Finish: Delivers a sharp, stealthy look that complements dark shell designs or adds a striking contrast to bright graphics.
• White Finish: Provides a clean, traditional motorsport aesthetic that blends flawlessly into standard white factory finishes.

Key Performance Features

• Authentic Arai Hardware: A genuine factory-produced accessory manufactured to Arai's legendary quality and safety standards, ensuring a perfect contour-matched fit.
• Targeted GP-J3 Fitment: Designed exclusively to match the unique curvature and ventilation ports of the Arai GP-J3 helmet series.
• Optimised Airflow Exchange: Actively channels high-velocity oncoming air into the helmet’s upper ventilation pathways, reducing heat build-up and keeping you comfortable under pressure.
• Simple Trackside Refurbishment: Ideal for replacing broken, lost, or worn-out ventilation ducts to maintain peak acoustic and cooling performance inside the cockpit.

Please Note: This listing is for a single top duct component. Before applying the replacement duct, ensure the helmet's surface is completely clean, degreased, and entirely free from old adhesive residue, wax, or polish to guarantee a permanent, track-safe bond.
