Seibon HD18AUA5-OE OEM-Style Carbon Fiber Hood for Audi - A5 S5 RS5

The Seibon HD18AUA5-OE is an OEM-style carbon fiber hood engineered as a direct-fit upgrade for the 2018–2024 Audi A5, S5, and RS5. Replacing the factory steel hood with this lightweight carbon fiber unit reduces front-end mass for improved handling dynamics while delivering an aggressive, show-ready appearance straight out of the box — no painting required.

Key Features:

• 3K 2x2 Twill Weave Carbon Fiber — Professional-grade fabric construction for a premium, consistent weave pattern appearance
• Exceptional Carbon/Resin Ratio — Optimized layup process produces high stiffness and added structural strength
• Show-Ready Gloss Clear Coat — Seibon's proprietary glossy clear coat finish is guaranteed not to chip or flake
• Fiberglass Skeleton Understructure — Fiberglass substructure bonded to the underside provides rigidity and support (matte black enamel finish)
• OEM Hardware Compatible — Mounts using factory hardware for a precise, rattle-free fit
• Hand-Crafted Construction — Each hood is individually built and passes Seibon's multi-step quality control inspection process

Important Installation Notes:

• Hood pins are required
• A heat shield is required
• Do not use stock hood shocks, dampers, struts, or springs — aftermarket gas struts are required
• If painting is desired, normal pre-paint preparation (sanding and primer) is required
• Occasional minor surface blemishes may be present as a result of the hand-manufacturing process; these can typically be addressed during pre-paint prep

Backed by Seibon's clear-coat warranty and fitment guarantee, the HD18AUA5-OE delivers the craftsmanship and precision fitment that have made Seibon Carbon one of the most recognized names in aftermarket carbon fiber body components.
