The Boundary 14mm billet oil pump gear fits 2014–2021 Subaru WRX models equipped with the FA20F turbo 2.0L engine (WRX only) and replaces the factory oil pump drive gear. As a billet unit sized to the original 14 mm specification, it restores proper engagement of the oil pump drive and is intended for direct-fit service during pump or engine maintenance where the OEM gear requires replacement.
