Seibon HD17AUA4-OE OEM-Style Carbon Fiber Hood for Audi - A4 S4 B9

The Seibon HD17AUA4-OE is an OEM-style carbon fiber hood engineered as a direct-fit, lightweight replacement for the Audi A4 and S4 (B9 chassis, 2017–2024). Designed to mirror the factory hood's clean profile, this upgrade delivers meaningful weight reduction over the stock steel hood while preserving the refined, understated look of the original design.

Constructed using 3K 2x2 twill weave carbon fiber fabric, the hood features a consistent weave pattern throughout and a glossy clear coat finish that is ready to install and display without any additional painting required. Seibon's production process achieves an exceptional carbon-to-resin ratio, resulting in a panel that is both rigid and strong. The clear coat is formulated to resist chipping and flaking over time.

Key Features:

• OEM-style profile — matches factory hood contours for a stock appearance in carbon fiber
• 3K 2x2 twill weave carbon fiber construction for consistent pattern and high stiffness
• Glossy clear coat finish — no painting required, chip- and flake-resistant
• Significant weight reduction versus the OEM steel hood
• Mounts using OE hardware and factory mounting points
• Backed by Seibon's fitment guarantee and clear coat warranty

Installation Notes: Professional installation is recommended. Hood pins and a heat shield are required. Do not use stock gas struts or hood dampers — the reduced weight of carbon fiber components may prevent proper closing and can cause damage or cracking if original spring-loaded mechanisms are retained.
