Protect the trunk and cargo area of your 2025 Kia K4 with the WeatherTech 421837 Gray Cargo Liner. Computer designed for a precise vehicle-specific fit, this cargo liner helps shield your interior carpeting from spills, dirt, grease, moisture, and everyday wear. The raised perimeter lip contains messes and helps prevent them from spreading onto surrounding trim or flooring, making it a practical solution for daily driving, road trips, grocery runs, pet transport, and hauling equipment.
The WeatherTech Cargo Liner is made from a proprietary custom-blended thermoplastic olefin (TPO) that combines durability with flexibility. Its wear-resistant construction is designed to withstand demanding use while remaining flexible through temperature extremes. A textured surface helps keep groceries, luggage, tools, and other cargo from shifting during transit, while the gray finish provides a clean, understated appearance that complements the vehicle interior. The liner is molded to follow the contours of the Kia K4 cargo area for dependable coverage and a secure fit.
Installation is quick and straightforward, with no special tools required. When cleaning is needed, the liner can be removed and rinsed or wiped down for convenient maintenance. Its durable design helps preserve the original cargo-area carpet and supports long-term interior protection without interfering with normal vehicle use. For added bumper coverage while loading or unloading personal items or pets, a compatible WeatherTech Bumper Protector may be used with the cargo liner; bumper protection is a separate accessory. This gray WeatherTech liner is an effective upgrade for Kia K4 owners who want reliable cargo-area protection and easy cleanup.
