C8 Corvette Billet Coolant Cap Cover – Black, Blue or Red (2020+)

Complete the look of your C8 Corvette engine bay with a precision-machined Billet Aluminum Coolant Cap Cover.

Designed to snap directly over the existing OEM coolant cap, this is a simple way to replace the factory plastic appearance with a cleaner, more premium finish.

Billet Aluminum Construction

Machined from 6061 billet aluminum, the cap cover provides a solid, high-quality appearance while retaining the factory coolant cap underneath.

Choose from three anodized finishes:

• Black
• Blue
• Red
