Diagram Ref No 1

Installed inside the 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.

Diagram Ref No 8

Also described as a quarter-panel splash shield, the liner sits inside the left rear wheel housing and forms a protective barrier between the rotating tyre and the vehicle body, suspension area and surrounding components.

It helps shield the inner wheel arch from:

• Stones
• Gravel
• Mud
• Water spray
• Road salt
• Dirt and debris

What This Product Does:
The rear wheel housing liner protects areas behind the wheel that would otherwise be directly exposed to debris thrown from the tyre.

Its main functions include:

• Protecting inner bodywork from stone impact
• Reducing mud and water ingress
• Helping protect nearby wiring and fittings
• Reducing dirt accumulation around the wheel housing
• Helping prevent damage to painted metal surfaces
• Reducing wheel-arch noise
• Maintaining the factory wheel-housing layout
• Helping keep surrounding components cleaner

Although it is not a structural suspension component, it provides important protection for the wheel-arch area.

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

Common symptoms include:

• Cracked plastic
• Split or torn sections
• Missing pieces
• Damaged mounting holes
• Liner hanging down
• Rattling from the rear wheel arch
• Flapping noises at speed
• Scraping or rubbing noises
• Liner contacting the tyre
• Missing clips or fasteners
• Heavy abrasion marks
• Distorted or warped liner sections
• Excessive dirt collecting behind the panel
• Water entering areas normally protected by the liner

A liner can remain partly attached while still being too damaged to provide proper protection.

Why Replacement Matters:
A damaged or missing wheel housing liner exposes the inner wheel arch to increased contamination and impact.

Continued use may contribute to:

• Stone damage
• Paint deterioration
• Increased corrosion risk
• Dirt accumulation
• Damage to nearby wiring or fittings
• Increased wheel-arch noise
• Further damage to adjoining panels
• Loose liner sections contacting the tyre

Replacing the liner restores the protective barrier originally designed into the vehicle.
