Billet Oil Pump Gear Set Honda H22 2.2L 4-Cyl.

The Billet Oil Pump Gear Set Honda H22 2.2L 4-Cyl. is a precision-engineered replacement for enthusiasts and mechanics seeking to upgrade or restore the lubrication system on high-performance Honda engines. This gear set addresses the critical need for reliable, durable oil delivery in modified H22 engines where stock components may suffer wear or inadequate flow under elevated RPM and boost conditions.

Machined from billet material, this oil pump gear set offers superior durability and dimensional stability compared to cast OEM alternatives, resisting wear from extended high-RPM operation and synthetic oil circulation. The precision tolerances maintain optimal clearances within the pump housing, ensuring efficient volumetric delivery without excessive leakage or pressure drop. Boundary Racing's design accounts for the specific geometry and timing requirements of the H22 engine family, guaranteeing proper meshing with the crankshaft drive and consistent performance across a wide range of operating temperatures and viscosity grades.

H22 owners running mild to aggressive modifications—including turbo or supercharger builds, engine swaps, or simply preventative maintenance on aged engines—benefit most from this upgrade. Installation requires engine disassembly to access the oil pump, making it ideal for those who are comfortable with engine work and looking to enhance their vehicle's performance.
