Finish off your B-series engine bay with this billet valve cover nut and washer seal kit, designed specifically for B16 and B18 VTEC engines. This upgrade replaces the factory rubber washers and hardware with precision-machined aluminum components for improved durability, oil sealing, and a cleaner, performance-focused appearance.
