Improve airflow and comfort inside your van with the Terrawagen Bug Barrier Window Vent, designed for Mercedes Sprinter, Ford Transit, and Ram ProMaster vans. These durable vent inserts allow fresh air to circulate through your cabin while keeping insects and debris out, making them a must-have upgrade for van life, camping, and overland travel. Each vent is constructed from all-weather ABS plastic and features a built-in mesh screen over every opening to prevent bugs and critters from entering your vehicle. The carefully engineered design fits securely into the window channel and allows you to drive with the vents installed thanks to the gap-free fit that helps minimize wind noise. The Bug Barrier also provides additional shade and ventilation, helping reduce heat buildup in the cabin while creating a comfortable cross-flow breeze when both vents are installed. Installation takes only seconds—simply roll down the window, twist the vent into position, and roll the window back up to lock it in place. Each set includes one driver-side vent and one passenger-side vent, allowing balanced airflow across the cabin. For convenient storage and protection when the vents are not in use, Terrawagen also offers optional storage bags designed specifically for Bug Barrier vents.
