Aston Martin Vantage Front Bumper KY6317626AA

part number KY63-17626-AA identifies the Front Bumper Splitter Assembly for the second-generation Aston Martin Vantage (2018–2024).

This component is the lower aerodynamic “lip” that attaches to the bottom of the main front bumper cover. It is a critical part of the car’s high-speed stability and cooling management.

1. Finish Options & Variations

The suffix of the part number denotes the specific material or finish of the splitter. The -AA version is the standard high-durability finish.

• KY63-17626-AA: Standard Black / Graphite finish (textured or matte plastic/composite).

• KY63-17626-BA: Often refers to the Graphite or “Dark” finish variant.

• KY63-17626-CA: The premium Gloss Carbon Fiber version (significantly more expensive).

2. Technical Details

• Aerodynamics: Designed to increase front-end downforce by splitting the airflow, forcing high-pressure air over the car and creating a low-pressure zone underneath.

   

• Vane Compatibility: This specific assembly is designed for the Mesh Grille style front end. If you have the “Vaned Grille” facelift (the traditional horizontal slats), the splitter mounting points and shape are slightly different (MY63 prefix).

• Ground Clearance: Because this is the lowest point of the car’s nose, it is the most frequently damaged exterior part due to steep driveways or curbs.

3. Pricing & Market Value (2026)

The price varies drastically depending on whether you choose the standard black version or the carbon fiber upgrade.

Maintenance Tip: The “Scrape” Solution

Since the KY63-17626-AA is prone to scraping, many owners install “Sliplo” or “Scrape Armor” skid plates on the underside of the new splitter before installation. This sacrificial layer of high-density plastic can save you from having to replace the entire $1,500 assembly after a single bad encounter with a speed bump.
