Upgrade a small but critical engine bay component with this precision-machined aluminum brake fluid reservoir cap. Designed as a direct replacement for the factory plastic cap, this upgrade improves durability, pressure management, and overall engine bay presentation—perfect for both daily-driven and performance-focused builds.

Why Upgrade?

Factory plastic brake fluid caps can deform over time and struggle to manage pressure changes during aggressive driving or track use. This aluminum cap offers a stronger seal, improved pressure equalization, and a refined OEM+ appearance that complements modern MQB and MQB-Evo platforms.

Key Features:

• Billet 6061 Aluminum Construction – Lightweight, rigid, and significantly more durable than factory plastic.
• Improved Pressure Equalization – Helps manage pressure changes caused by pad wear and high brake temperatures.
• EPDM Sealing Gasket – Provides a reliable, corrosion-resistant seal for long-term use.
• Anodized Finish – Enhances corrosion resistance while maintaining a clean OEM+ look.
• Non-Slip Design – Makes brake fluid checks and maintenance quick and easy.
