Boundary FA20D-12MM-OPG-M Billet Oil Pump Gear Set with MartenWear Treatment

The Boundary FA20D-12MM-OPG-M is a 12mm billet oil pump gear set featuring Boundary's proprietary MartenWear surface treatment, engineered as a high-performance upgrade for the FA20D 2.0L engine. Designed to replace the factory powdered metal gears that are known to wear prematurely under high-RPM and high-load conditions, this gear set delivers superior reliability and oil pressure consistency for performance and track applications.

Key Features:

• MartenWear Proprietary Heat Treatment – Boundary's exclusive in-house MartenWear process applies a second stage of heat treatment to the exterior surface, creating an exceptionally hard and wear-resistant finish that dramatically extends service life under demanding conditions
• 12mm Extended-Width Billet Gears – The 12mm gear profile increases oil flow volume compared to the stock gear set, helping maintain consistent oil pressure at high RPM and reducing the risk of oil starvation during spirited or on-track driving
• CNC-Machined Billet Steel Construction – Precision-machined from high-grade billet steel in Boundary's Dallas, TX facility using high-end American-made machining centers, ensuring superior dimensional accuracy and strength over OEM cast or sintered components
• Direct OEM Replacement Fitment – Installs directly in place of the factory FA20D oil pump gears with no permanent modifications required
• Manufactured in the USA – Produced entirely in-house at Boundary's Dallas, Texas facility for consistent quality and precision

Whether you're building a dedicated track car or a modified street vehicle, the FA20D-12MM-OPG-M is one of the most critical oiling system upgrades available for the FA20D platform. Boundary's in-house manufacturing capabilities ensure the precision required for reliable inter-meshing gear pump performance.
