KS Tuned Boundary Racing Honda H&F Series H22A1 H22A4 H23A F20B F22 F23 Billet Oil Pump Gears

After years of testing in conjunction with Boundary Pumps we finally have a solution for broken oil pump gears, and they're available only from KS Tuned!

The problem: Factory oil pump gears have been known to break in extreme conditions such as excessive rev limiting, extended high-RPM use and especially in the case of a loose flywheel. This breakage is caused because the OEM oil pump gears are made from sintered steel. Sintering is a cost-saving process where powdered steel is pressed into a solid form, which provides a hard, but brittle material.

The solution: The 4140 billet oil pump gear was conceived to alleviate these problems while also providing a bump in oil pressure across the RPM range. Testing shows stable oil pressure beyond 10,000 RPM! Further, the Boundary Oil Pump Gears are made from billet 4140 with a yield strength 18x stronger than OEM sintered steel!

The price includes the OIL PUMP GEARS ONLY (inner & outer gears included) and are designed exclusively for the OEM Honda Oil Pump Housing! We strongly recommend these oil pump gears be used only in a brand new OEM Honda oil pump housing.

*Fits all H-series engines and F20B, F22, F23 using the OEM Honda housing.
