Description
Upgrade your engine bay with the MMX Performance Billet Engine Oil Filler Cap (MMR03-0102-DA) — the ultimate solution for preventing oil seepage caused by worn or faulty factory caps. This internally sprung cap locks into place with a satisfying click, offering a secure seal and eliminating common issues with loose or leaking oil filler caps.
Engineered for strength and aesthetics, this cap is CNC-machined from 6061 aerospace-grade aluminum, then polished and gloss-anodized for long-term durability and heat resistance. Its ergonomic design provides a reliable grip for easy removal and installation, even with oily hands.
This cap is not just about looks — it's a functional upgrade that helps maintain engine cleanliness and health by preventing the subtle oil leaks that can lead to larger issues over time.
