Wheel Arch Lining, Front.
Restore the inner protection of your front wheel arches with these genuine OEM liners for the Porsche 911 (997) series.

  • Porsche 997 MK1 Carrera 4 3.6L 2006-08

What This Product Does:

  • Protection: Shields the inner wheel arch, suspension components, wiring, and bodywork from debris, mud, water spray, stones and grime kicked up by the front wheels.
  • Acoustic and Cleanliness: Helps keep the arch area quieter (reducing wheel-well noise) and cleaner by providing a barrier rather than leaving components exposed.
  • Finish & Fitment: Ensures that the bodywork has correct finishing inside the arch; if the liner is missing or damaged, the arch area looks incomplete, components are exposed and corrosion risk is higher.

Symptoms & Signs You Might Need Replacement:
  • Visible damage or missing liner inside the front wheel arch: e.g., split or cracked plastic, detachment, missing fasteners, or the liner entirely absent.
  • Excessive dirt, debris or corrosion inside the wheel arch or on inner body panels — if the liner is compromised, the arch is less protected.
  • Unusual wheel-arch noise or increased road noise: If the liner is loose or missing, suspension components may be exposed and road spray or debris may enter areas that were previously shielded.
  • Wear from age: These liners may become brittle, cracked or partially detached with age, particularly on cars used in regions with road salt or heavy use.

Why Replacement Matters:
  • Component protection: Replacing a damaged liner protects suspension, brake lines, wiring and body panels from damage and corrosion.
  • Vehicle integrity and value: For premium or collector cars like the 911, original-fit liners help maintain appearance, fitment completeness and resale value.
  • Finish and appearance: Ensures that the wheel arch area looks correct, aligns with bodywork, and the interior of the arch isn’t exposed.
  • Noise/Vibration: Proper liners help reduce ingress of road spray, minimise wheel-well noise and contribute to a refined driving experience.
  • Preventative maintenance: Installing a new liner before serious damage occurs is cheaper than dealing with rust, debris-damage or incorrect suspension component exposure later.
