This is an ultra high quality Rotor Shaped Oil Filler Cap adds that finishing touch to any RX8. We CNC machined these ultra high quality oil caps from aircraft grade billet aluminum. The oil seal material is designed to provide a perfect seal for years to come. Unlike anodizing, our Nickel Plating will look good for years with just a quick wipe of a rag to remove dust and dirt.  Engraved with a RX7 logo and the seal grooves. We package these premium parts in a custom fitted, foam lined box.
