Audi S4/A4 B9/B9.5 (2015-2023) Prepreg Dry Carbon Fiber Front Air Canard

Designed for Audi S4/A4 B9 and B9.5 (2015-2023) sedan and Avant owners, this Prepreg Dry Carbon Fiber Front Air Canard set mounts to the outer sides of the front bumper and brings race-grade aggression to your sport sedan or Avant. Manufactured in Europe and quality-controlled by BYC Performance, this Audi B9 carbon canard set bonds directly to OEM bumper surfaces — no cutting, drilling, or modification required.

If you're working on an Audi S4 B9 tuning or A4 B9.5 modifying project and want sharp side canards on the front bumper, this dry carbon front canard set is for you. Autoclave-cured prepreg carbon is noticeably lighter than wet-lay parts, with superior structural integrity and outstanding UV resistance. The aggressive canard profile complements the S4 B9's 3.0 TFSI V6 single-turbo (349-354 hp) sport-sedan character and adds standout track-style detail to street and circuit driving alike.

Key Features

• Prepreg Dry Carbon Technology: Pre-impregnated plies cured in an autoclave under high heat and pressure for a more consistent weave.
• Race-Inspired Design: Aggressive winglet profile mounted to the outer front-bumper face, noticeably lighter than equivalent factory plastics.
• Race-Grade Strength: Carbon fiber offers very high strength for its weight.
• Aerodynamic Effect: Redirects front-bumper airflow around the wheel arch and adds front-axle downforce at speed.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under a high-gloss UV-protective clear coat.
• Adhesive Mount: Pre-applied 3M double-sided tape backing for clean, permanent installation.
• UV & Chemical Protection: Clear coat resists fading, cracking, fuel splash, and road tar.

Prepreg Dry Carbon vs. Wet Carbon — Which Is Better?

Most aftermarket carbon parts use wet lay-up, with resin applied by hand and cured at room temperature. Prepreg dry carbon:

• Autoclave-cured under high heat and pressure → a more consistent weave
• A controlled resin ratio → lighter and stronger
• The production method widely chosen in motorsport
• Minimal UV fading over years of use
