Key features and why they matter

• CNC-machined billet construction — Delivers consistent dimensional accuracy for a precise fit and a reliable sealing surface, minimizing the chance of deformation or thread wear over time.
• Included O-ring — Ensures a tight, reliable seal against the filler neck to help prevent oil seepage and ingress of contaminants during normal operation.
• Available in red (also offered in black) — Provides a durable, colored finish for visual distinction in the engine bay while allowing selection to suit vehicle aesthetics.
• Mishimoto branding on top — Identifies the component as part of a known aftermarket parts program and signals consistent manufacturing standards to technicians and enthusiasts.

Designed to replace the factory oil filler cap on compatible applications, this cap offers a direct-fit form factor and simple installation without modification. The billet construction and sealed interface are aimed at maintaining engine bay reliability while offering a refined appearance.
