ECS Tuning 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. This cap is not only designed to look great, but fit and function just like the factory part with improved ergonomics.
Requires the OEM pressure relief valve to be transferred. See the below PDF for the proper procedure!
