The Boundary Racing FA20F 14mm Billet Oil Pump Gear (FA20F-14MM-OPG) is engineered to strengthen one of the most critical components in the FA20F engine's lubrication system. Precision CNC-machined in the USA from premium chromoly billet steel, this direct replacement oil pump gear is significantly stronger than the factory powdered metal gear, making it an ideal upgrade for high-horsepower builds, track cars, and performance-driven street vehicles. Designed specifically for the 2015-2021 Subaru WRX FA20F 2.0L Turbo, the 14mm gear increases oil volume while providing improved oil pressure and enhanced engine protection under extreme operating conditions.
Each gear is surface hardened and mirror finished to reduce friction and wear while maintaining consistent oil pressure throughout the engine's RPM range. Boundary Racing's precision manufacturing and patented gear design provide exceptional durability for engines running increased boost, larger turbochargers, and sustained high-RPM operation. Backed by a Lifetime Warranty, the FA20F-14MM-OPG is built to deliver long-term reliability for serious Subaru enthusiasts.
