Restore the inner protection of your front wheel arches with these genuine OEM liners for the Porsche 911 (997) series. The left side part 99750420301 covers the rear section of the front left wheel arch, and the right side part 99750420401 covers the rear section of the front right arch. These moulded plastic liners are designed to fit precisely, shielding suspension and body components from debris, water spray and contamination while improving acoustic and aesthetic finish inside the arch area.

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.
- 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.
- 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.
