Boundary FA20F-14MM-OPG-M FA20F 14mm Billet Oil Pump Gear MartenWear Treated

The Boundary FA20F-14MM-OPG-M is a 14mm billet oil pump gear with proprietary MartenWear dual heat treatment, engineered as a high-performance upgrade for the FA20F 2.0L flat-four boxer engine. Designed to replace the factory powdered metal gear, this billet oil pump gear delivers superior strength, improved oil pressure, and lasting reliability for high-demand street and track applications.

Key Features:

• MartenWear Treatment: Boundary's proprietary dual-stage heat treatment hardens the exterior gear surface to Vickers 620–720 (Rockwell C 55–60), producing an extremely hard, long-wearing surface that is proven wear-free at surface speeds up to and beyond 13,000 RPM
• Chromoly Billet Construction: Precision CNC-machined in the USA from premium 4140 chromoly billet steel — significantly stronger than the OEM powdered metal gear
• 14mm Gear Design: The upgraded 14mm gear increases oil volume delivery compared to the stock 10mm gear, improving idle oil pressure and overall lubrication under boost and high-RPM conditions
• Mirror Finished & Surface Ground: ColdFlow mirror polish reduces friction and wear; gears are surface ground for precise fitment and matched as a set for optimal performance
• Blueprinting Report Included: Each gear set is individually hand-inspected, machine-inspected, and hardness-tested, with a blueprinting report included
• Direct Replacement: Drop-in replacement for the factory oil pump gear — no drilling or permanent engine modifications required
• Lifetime Warranty: Backed by Boundary's limited lifetime warranty
• Made in the USA: Manufactured at Boundary's production facility in Royse City, TX

The FA20F-14MM-OPG-M is the MartenWear-treated variant of Boundary's FA20F billet oil pump gear, making it the ideal choice for builds running increased boost, larger turbochargers, or sustained high-RPM operation where maximum gear durability is critical.
