CRL FW623R Dual-Vent Rear Quarter Window – Sprinter 170 & 170EXT (2007-2026) Passenger Side

Airflow inside a Sprinter van depends on having a defined intake and exhaust path. Front windows bring air into the vehicle while rear quarter vents allow trapped heat to escape. Without a rear outlet, interior temperature remains elevated and ventilation efficiency is reduced.

The CRL FW623R is a vehicle-specific rear quarter dual-vent window designed for long wheelbase Sprinter vans. It provides controlled airflow while maintaining a factory-style exterior appearance.
