This solid titanium cap cover fits right over the OEM brake master cap and adds a unique titanium look to your engine bay. Each of our caps is professionally CNC machined from a single piece of 6AL-4V Grade 5 Titanium. Each cap is laser-etched with the circular JDC logo on the top and is hand polished before receiving our proprietary cold anodizing treatment for colors that will last for a lifetime! Custom logos are available!
