This rear window spoiler gives the K5 a sharper and more complete exterior look while flowing naturally with the factory body lines.

Installation This rear window spoiler installs directly onto the top of the trunk using automotive-grade double-sided tape. Before installation, clean the surface thoroughly, test fit the spoiler, and confirm placement before applying pressure. For best results, install in a warm environment and allow the adhesive to fully bond before washing the vehicle or driving in harsh weather. 🏁 Why Upgrade Your Kia K5 Rear Window Spoiler? The rear window spoiler is one of the best exterior upgrades for the Kia K5 because it instantly adds a more aggressive and complete look to the rear of the vehicle. By extending the roofline and sharpening the upper rear profile, this spoiler gives your K5 a sportier appearance while keeping the design clean and OEM+. It is the perfect finishing piece when paired with an AFD rear diffuser, side skirt extensions, front lip, or full aero kit.
