AVS In-Channel Ventvisor Side Window Deflectors are designed to complete the look of your vehicle adding subtle style while maintaining the functionality you desire from a side window deflector. The Ventvisor installs in the window channel for a streamlined appearance, but still allows fresh air to naturally circulate through open windows while keeping the rain and wind out. There is no special hardware needed and no drilling required, the In-Channel’s patented design easily secures into the window channel or along the rubber seal with pre-applied 3M automotive tape. Absolutely no tape touches your vehicle’s finish. Additionally, the product keeps the sun out of your eyes and allows you to keep your window cracked while parked, keeping the interior cooler.
