Mercedes-Benz AMG A45 W177 (2018+) Prepreg Dry Carbon Fiber Roof Spoiler

Engineered for Mercedes-AMG A45 W177 (2018+) hatchback owners, this Prepreg Dry Carbon Fiber Roof Spoiler adds an AMG silhouette to your hatch's roofline and stabilizes the rear axle at high speed. Manufactured in Europe and quality-controlled by BYC Performance, this W177 carbon roof spoiler fits OEM roofline mounting points directly.

If your A45 W177 tuning project demands a motorsport-inspired roof spoiler, this dry carbon roof spoiler is built for you. The W177-generation A45 AMG runs the world's most powerful production 4-cylinder: the M139 2.0L turbo (387-421 hp S trim) — your roofline should match that legacy.
