The Boundary MartenWear-treated billet oil pump gear is specified for Honda B18 I4 1.8L orbit-style pumps. Machined from billet material and treated for wear resistance, this gear is intended as a direct replacement component for the orbit pump assembly. It’s presented as an engineered internal gear upgrade for that specific engine application, supporting oil delivery components without altering external engine systems.
