Show original supplier description
The Seibon CWII-Style Carbon Fiber Hood is a premium aftermarket component meticulously crafted for the 2008-2014 Subaru Impreza WRX and STI models with GR and GV chassis. Its design incorporates features that promote heat extraction, enhancing the functionality of the engine bay. The construction prioritizes a high carbon-to-resin ratio for superior product stiffness and strength, ensuring durability and longevity. Installation of this Seibon carbon fiber hood requires the use of OE hardware and is recommended to be performed by a professional due to the specialized nature of carbon fiber components. The CWII style provides a distinct visual upgrade, reflecting Seibon's commitment to both form and function. Seibon Carbon, with over two decades of experience, ensures rigorous quality control throughout their manufacturing process. Fitment is specific to 4-door hatchback and 4-door sedan variants. While the product aims for a direct bolt-on replacement, it is crucial to confirm fitment with your specific vehicle details. The manufacturer also provides a California Proposition 65 warning regarding potential exposure to Nickel.
