CRL FW626L Dual-Vent Rear Quarter Window – Sprinter 144" Wheelbase (2007-2026) Driver Side

Effective ventilation inside a Sprinter requires both intake and exhaust airflow locations. Front and sliding door windows allow fresh air in, while rear quarter vents allow warm air to leave the vehicle. Without a rear outlet, airflow stagnates and interior temperature rises.

The CRL FW626L is a vehicle-specific rear quarter dual-vent window designed for the 144" wheelbase Sprinter. It provides adjustable airflow while maintaining a traditional factory-style appearance.
