Show original supplier description
The RW Carbon Arkym Style Carbon Fiber Diffuser offers an aggressive, race-inspired aesthetic upgrade for the rear of your Mercedes-Benz W204 C-Class. Constructed from genuine 2x2 carbon fiber fabric, this diffuser is meticulously handcrafted and finished with a clear coat to provide a deep, brilliant shine while offering UV protection. Installation is recommended to be performed by a professional due to the nature of the modification. Please note that proper fitment requires the removal of the rear bumper. The diffuser is compatible with specific Mercedes-Benz W204 models. It fits all pre-facelift C63 AMG Sedan models from 2008-2011. It also fits C300 and C350 Sedan models from 2008-2011, provided they are equipped with the AMG Rear Bumper. If your C Class has a dual exhaust, you will need to use AMG C63 tips or aftermarket quad exhaust tips for proper integration.
