Diagram Ref No 1

Installed inside the left-front wheel arch, the liner creates a protective barrier between the rotating wheel and vulnerable bodywork, cooling components and surrounding hardware.

In addition to protecting the wheel housing from road debris and water spray, this particular liner forms part of the vehicle's airflow-management system, helping direct air around the radiator and toward the braking area.

What This Product Does:
The front wheel housing liner helps protect components inside the wheel arch while controlling airflow around the front of the vehicle.

Its functions include:

• Protecting inner bodywork from stones and debris
• Reducing direct water and mud spray
• Shielding wiring and nearby components
• Helping prevent road salt and dirt accumulation
• Helping manage airflow exiting the radiator area
• Directing cooling air toward the braking system
• Reducing wheel-arch noise
• Maintaining the original Porsche underbody and wheel-arch layout

Although the liner is not a structural suspension component, correct fitment is important for protection, airflow and clearance around the front wheel.

Symptoms Of Wear Or Failure:
Wheel housing liners can become damaged through impact, age, tyre contact or incorrect removal.

Common symptoms include:

• Cracked plastic
• Split or torn sections
• Broken mounting tabs
• Enlarged or torn mounting holes
• Missing pieces
• Liner hanging down
• Rattling from the front wheel arch
• Flapping noises at speed
• Scraping or rubbing noises
• Tyre contact with the liner
• Missing screws or plastic fasteners
• Distorted panel shape
• Heavy abrasion
• Damaged air vents or ducts
• Increased debris collecting behind the liner

A liner may still appear mostly attached while being sufficiently damaged to interfere with tyre clearance or airflow.

Why Replacement Matters:
A damaged or missing liner exposes normally protected areas to stones, moisture and road contamination.

Continued use may contribute to:

• Damage to painted inner bodywork
• Increased corrosion risk
• Contamination around wiring and brackets
• Dirt accumulation around cooling components
• Reduced effectiveness of brake-cooling airflow
• Increased wheel-arch noise
• Loose plastic contacting the tyre
• Further damage to adjoining underbody panels

Replacing the damaged liner restores both the protective barrier and the original airflow path.
