Wheel Arch Liner (Inner Fender)
The wheel arch liner is a plastic or felt shield inside the wheel arch that protects the body from water, stones and dirt.
What is Wheel Arch Liner (Inner Fender)?
It is held with clips and screws. Felt liners also reduce road noise. Many components behind it, such as headlights, are serviced through openings in the liner. Liners are often removed to access headlight bulbs, washer reservoirs or corroded parts. Missing clips should be replaced so the liner does not flap at speed. Some liners have aerodynamic shapes that reduce drag and noise.
How it works
The liner keeps spray thrown up by the tyre away from the body and engine bay.
Why it matters for your car
A loose or missing liner exposes the body to corrosion and can rub on the tyre. Liners can trap dirt and moisture, so cleaning behind them helps prevent rust.
