The Perrin blue oil fill cap is a direct-fit replacement for Subaru engines in 2002–2025 Impreza/WRX/STI and 2013–2026 Crosstrek, BRZ, FR‑S and GR86 models. It offers a color-matched upgrade to the factory oil fill opening and a finished appearance for the engine bay. The cap provides a simple, bolt-on swap for service or cosmetic enhancement when the original fill cap is replaced.
