New Audi/VW Billet Expansion Tank Cap - Black Anodized
The details matter! Dress up your engine bay by removing the cheap and generic plastic cap and replacing it with a full billet cap - not just an overlay. Designed and engineered in-house by ECS Tuning, this precision machined billet aluminum cap is just what you need! Our caps are made out of a solid piece of 6061-T6 billet aluminum and Type II anodized for appearance and corrosion resistance.
Lose the plastic!
