The factory Subaru oil cap is plastic, it discolors, degrades, and looks worse over the life of the engine. The GrimmSpeed delrin cap does not share those failure modes. It threads correctly, maintains its appearance, and handles heat cycling without degrading. Delrin has much lower thermal conductivity than aluminum, it remains cooler to the touch after the engine has been running, making warm-engine oil checks noticeably more comfortable.

Installation is a direct thread swap at the oil filler neck, no tools, no modifications. Engine bay builds benefit from attending to small visible details like the oil cap, they accumulate into a finished overall appearance.
