Product Details
The Boundary 14mm Billet Oil Pump Gear for 2014–2021 Subaru WRX FA20F 2.0L Turbo engines is engineered to provide increased reliability and peace of mind in both stock and high-performance builds. Factory oil pump gears are a known failure point under elevated RPM and increased load, especially in modified applications. Boundary’s upgraded billet steel gear is precision-machined to handle higher stress levels while maintaining consistent oil pressure and improved oil volume. The 14mm design delivers enhanced lubrication to critical engine components, helping reduce the risk of oiling-related failures during aggressive driving, track use, or sustained high-RPM operation. This direct-fit oil pump gear is an essential upgrade for WRX owners focused on engine longevity and durability.
