What is the name of the plastic next to the fender?

The plastic next to the fender is called the fender liner. Here is more related information: 1. The function of the fender: The fender is also known as the wing panel. The fender is located on the outside of the car body near the wheels. Its function is to reduce the drag coefficient based on fluid dynamics, making the car drive more smoothly. According to the installation position, it is divided into the front fender and the rear fender. The front fender is installed above the front wheels. Since the front wheels have a steering function, it is necessary to ensure the maximum limit space when the front wheels turn. Therefore, designers will use the "wheel jump diagram" to verify the design dimensions of the fender based on the selected tire model size. The rear fender does not have the problem of wheel rotation contact, but for aerodynamic considerations, the rear fender is slightly arched and convex outward. 2. Explanation of the fender: The fender (Fender) is also called the wing panel, which is a type of cover on motor vehicles and non-motor vehicles. It includes the front fender, front fender liner, front fender light, rear fender light, and radiator frame.
In my previous car, that plastic thing next to the fender was called a wheel arch liner. Its main function is to protect the wheel area from debris and mud splashing in, and to reduce noise. I remember one rainy day driving home when the wheel arch liner had aged and cracked, and muddy water sprayed all under the engine. Luckily, I went to the repair shop in time to get it replaced with a new one. This part is usually made of high-density polyethylene plastic, which is durable but can become brittle and crack under long-term wear. For daily maintenance, it's recommended to check for cracks or looseness when washing the car regularly. If it's damaged, it should be replaced to avoid affecting driving safety. I suggest car owners not to delay if they encounter similar issues. This small component may seem insignificant, but it can prevent major troubles.
With years of experience in car repair, the plastic part next to the fender is commonly referred to as the wheel arch trim or fender liner, with the industry term being wheel arch liner. It serves important functions like mud protection, water resistance, and absorbing vibration noise. During inspection, first visually check for deformations or cracks, then manually shake it to see if it's loose. If damaged, it's best to replace it outright rather than making do. Most available on the market are made of plastic or rubber, affordable and easy to install, allowing for DIY replacement. I once replaced one for a neighbor whose car frequently traveled rough roads, accelerating wear—it seemed minor but posed significant risks. It's advisable to give it a quick check before driving to ensure it's in good condition.
