About part number C1BB-16115-AB

An inner wing arch liner is a protective shield fitted inside the wheel arch on the left-hand side of the vehicle. It forms part of the bodywork and trim system, sitting between the road wheel and the main body structure. This plastic guard protects the engine bay and inner metal panels from road debris, water, mud, and stone chips. When it is intact and correctly fitted, it helps reduce road noise in the cabin and stops dirt from accumulating in hidden areas of the wing.

To confirm that this replacement liner is the correct item for your vehicle, you must match the part number directly. The manufacturer part number for this item is C1BB-16115-AB. On a component of this type, the number is usually stamped or moulded directly into the plastic surface on the back or along one of the outer edges. Checking that this exact number matches the code on your original part is the only way to ensure proper fitment.

These liners are commonly replaced after sustaining damage from road hazards, tyre blowouts, or minor front-end impacts, which can cause the plastic to crack, snap, or rub against the wheel. When fitting a replacement arch liner, you will typically need a set of compatible plastic trim clips, screws, or splash-guard retainers, as the original fasteners often break or go missing during removal.

About this kind of part: wheel arch liners

A wheel arch liner is the moulded plastic or felted shell inside a wheel arch that keeps water, salt and stones off the inner wing, the suspension and the wiring. It is hidden and it is not structural, but it is the part that decides whether the metal behind it rusts, so a missing or torn liner is a slow problem rather than a cosmetic one. Mudflaps, undertrays and the air ducts that feed the brakes are the same kind of part doing the same job elsewhere under the car.

Why people replace one

  • The liner has torn away from its clips, usually after a wheel has picked it up at speed, and it now rubs the tyre.
  • Road debris or a kerb has split the liner along an edge.
  • The clips and screws have rusted away or pulled through, so the liner hangs down and catches.
  • The liner was removed for a repair and never refitted, which leaves the inner wing exposed.
  • A felted liner has become waterlogged and heavy and has pulled itself off its fixings.

Fitting it

  • The wheel normally has to come off, and the car must be supported properly on axle stands rather than a jack alone.
  • A liner is held by a mixture of plastic screws, clips and expanding rivets around its edge, and most of them break on removal, so a set of fixings is worth having before starting.
  • Fit the fixings loosely around the whole edge first and tighten them afterwards, otherwise the last few holes will not line up.
  • With the liner out, it is worth looking at the metal behind it. A liner that has been missing for a while has usually exposed something worth seeing.

Making sure it is the right one

  • Match the part number moulded into the liner. Front and rear differ, the two sides differ, and a model with wider arches takes a different part again.
  • Count the fixing holes and compare their positions with the old liner. This is the quickest way to tell two similar liners apart.
  • Check whether yours has cut-outs or ducts for brake cooling, a sensor or a washer line. These vary by specification.
  • Compare the material. The same position is made as hard plastic on one version and as a felted shell on another, and they use different fixings.

What to look for in the photographs

A Part number — Moulded into the inner face. It is often the only difference between two liners that look the same.
B Fixing holes — The holes, slots and rivet points around the edge. Count them and compare the spacing with your own liner.
C Cut-outs and ducts — Any opening for brake cooling, a sensor or a washer line. These vary by specification and are part of the match.
D Edge condition — Look along the whole rim, particularly where the fixings pass through. This is where a liner tears out.
E Material — Hard plastic or a felted shell. They are not interchangeable and they take different fixings.
