Finish off your engine bay with a subtle but premium upgrade. This billet aluminum cap replaces the factory plastic cap with a precision-machined aluminum piece built for durability, clean aesthetics, and dependable sealing — whether your Miata is a daily driver, track car, or fully built showpiece. Machined from billet aluminum and finished with a corrosion-resistant anodized coating, this cap is designed to handle real engine bay heat cycles while maintaining a tight seal via a quality O-ring. A raised grip surface makes removal easy even when the engine is hot or you’re working with gloves. This is a simple upgrade that adds a refined motorsport look without sacrificing function — exactly the type of detail enthusiasts appreciate when building a complete Mazda performance package.
