Show original supplier description
The Willpak Rear Window Louvers 1577 are custom-molded to fit specific vehicles, offering a sporty and stylish enhancement to your car's exterior. Constructed from smooth ABS plastic, these louvers are designed to integrate seamlessly with your vehicle's design, reminiscent of classic muscle car aesthetics from the '60s, '70s, and '80s. Beyond their visual appeal, these louvers provide practical benefits. They increase interior privacy and help to lower cabin temperatures by reducing sun glare, thereby protecting upholstery from sun damage. Despite their angled design, they do not obstruct the driver's visibility. Willpak offers these louvers in several finishes, including Matte Black aluminum, textured black ABS, and smooth black ABS, with each option being completely paintable to match your vehicle's color scheme. Installation is straightforward, typically involving stainless steel hardware, 3M double-sided tape, or attachment under the trim, depending on the vehicle model. This specific model, the 1577, is designed to fit the 2015-2016 Ford Mustang. The product comes with a 36-month limited warranty.
