About part number N8B2-45431-BD

A boot side trim panel is an interior cover that fits inside the luggage compartment on the left-hand side of the vehicle. It conceals the bodywork, wiring looms, and rear wheel arch, giving the boot a finished appearance and protecting the metalwork from damage when carrying cargo. When the trim is installed correctly, it stays securely in place, helps to reduce road noise from the rear of the cabin, and provides a neat, clean surface inside the load space.

To ensure this is the correct part for your vehicle, you must match the part number N8B2-45431-BD directly with the number stamped or printed on your original trim panel. Part numbers on moulded plastic interior trims are typically stamped into the reverse side of the panel, so you may need to unclip the existing piece to view it. Matching this exact number is the only way to confirm correct fitment, as shape, clip locations, and cut-outs vary between different specifications.

People usually replace a boot side trim if the original panel is cracked, heavily scratched, or has broken mounting tabs that prevent it from sitting flush. When replacing this part, you often need replacement plastic trim clips or push-rivets, as these frequently bend or snap during removal of the old panel. A plastic trim removal tool is also useful to safely pry the trim away without damaging the surrounding interior panels or bodywork.

About this kind of part: trim mouldings

A trim moulding is a long, narrow strip that finishes an edge or a joint on the outside of a car: a door moulding, a sill cover, a wheel arch trim, a window finisher or a roof strip. Most are plastic, either painted to match the body or supplied in a textured black or a bright finish, and they clip to studs or to double-sided tape. They are cosmetic rather than structural, but they also cover the panel joint underneath, so a missing one leaves a gap where water and grit collect.

Why people replace one

  • A knock or a car wash has pulled the moulding away and broken the clips behind it.
  • The painted finish has chipped along the leading edge, which happens from stone strike on anything low down.
  • A textured black trim has gone grey and chalky in the sun, which cannot be cleaned back.
  • The double-sided tape has let go in the heat, so the strip lifts at one end and flaps.
  • A panel has been replaced and the original trim was broken getting it off.

Fitting it

  • A clipped moulding comes off by releasing each clip in turn from one end rather than pulling in the middle, where it will crack.
  • The clips themselves are usually separate parts and are normally replaced rather than reused, because they stretch once they have been off.
  • A taped moulding needs the old adhesive cleaned off the panel and new tape of the correct width, applied to a warm, dry panel.
  • Check which way up the strip goes before fitting. Many are handed and look symmetrical.

Making sure it is the right one

  • Match the part number. A moulding from the front door and one from the rear door of the same car are different lengths and different numbers, and so are the two sides.
  • If the trim is a wheel arch or a sill, check whether yours has openings for parking sensors. One without the openings cannot be used on a car that has them.
  • Compare the finish: the same moulding is made painted, in textured black and in a bright finish, and each is a separate number.
  • Count the clip positions along the back and compare them with the studs on your own car.

What to look for in the photographs

A Part number — Moulded or printed on the back face, usually towards one end.
B Clip positions — The row of clip seats or studs along the back. Count them and compare the spacing with your own car.
C Sensor openings — Openings for parking sensors, where the trim is an arch or a sill. Their presence or absence decides whether it fits your car.
D End profile — The shape of each end, which is what tells a front strip from a rear one and one side from the other.
E Leading edge — Look along the lower or forward edge, where stone chipping collects. It is the part a flat photograph flatters most.
F Tape or clip channel — Whether the back has a tape bed or a clip channel. These are not interchangeable.
