Bevinsee Billet Aluminum Coolant Cap – E9X/F3X Direct Fit Performance Upgrade €27,95

Bevinsee Billet Aluminum Coolant Reservoir Cap – Premium Upgrade for BMW E-Series & F-Generation

Upgrade your BMW's engine bay with this precision-engineered Bevinsee coolant cap. Factory plastic caps deteriorate from thermal stress, pressure cycling, and age, leading to leaks and overheating issues. This CNC-machined billet aluminum replacement offers superior durability, enhanced aesthetics, and engineered pressure relief compatibility — a true OEM+ upgrade.

Aircraft-Grade Billet Aluminum Construction:

  • 6061 Billet Aluminum: Significantly stronger and more heat-resistant than fragile factory plastic caps
  • CNC-Machined Precision: Manufactured to exacting tolerances ensuring perfect fitment with zero leakage
  • Anodized Surface Finish: Enhanced resistance to corrosion, UV fading, and thermal degradation
  • Professional Engineering: Latest-generation CNC technology ensures component quality

Smart Design — Retains Factory Pressure Relief Functionality:

  • Pressure Relief Compatible: Design allows you to easily transfer the factory pressure relief valve from your old cap to the new billet cap
  • Simple Assembly Process: Swap pressure relief valves in minutes with basic tools — no machine work required
  • Maintains OEM Performance: Preserves critical pressure regulation that keeps your cooling system operating safely
  • Replaces OEM Parts: Direct replacement for factory caps (part numbers 17117639020, 17117521071)
