trim piece. That black vinyl strip is available also on CZP but to do a perfect job, you'd need to remove your spoiler as it tucks under. I replaced mine with the spoiler still on but it was difficult and far from perfect. An extra set of hands help when it comes to applying the new one due to the length. I removed my old vinyl/stickers using a 3m spray label/adhesive remover and a plastic putty knife. If you use anything sharp like a razor blade, you risk digging into the paint. It's a time consuming task but certainly refreshes the rear end of the car.
As a tip, I measured where the "Nissan" and "Twin Turbo" decals were prior to removing the vinyl so that I could place them back in the exact same spots.
