CTS Turbo Billet Brake Fluid Reservoir Cap for MQB/MQL

The CTS Turbo Billet Brake Fluid Reservoir Cap replaces the factory plastic component with precision-machined billet aluminium construction. Designed specifically for MQB and MQL platform Audi vehicles, this cap offers enhanced durability and a refined underbonnet appearance. The anodised finish resists corrosion while maintaining a secure seal on your brake fluid reservoir. Direct bolt-on installation ensures perfect fitment across RS3, S3, TTRS and select A4 models without modification. An effective upgrade for workshops seeking improved component longevity and a professional engine bay presentation on performance-focused Audi applications.
