Cobb Subaru Oil Cap – Stealth Black (2002-2021 WRX, STI, Forester XT, Legacy GT)
The Cobb Subaru Oil Cap in Stealth Black replaces the factory plastic cap with durable billet aluminum construction. Designed for 2002-2021 Subaru WRX, STI, Forester XT, and Legacy GT models, it delivers a reliable O-ring seal to prevent leaks and contamination. The knurled edges ensure quick removal during oil changes, while the black anodized finish resists corrosion for long-term engine bay style.
