Description

The 4 Piston Racing 4P Ported H22 Oil Pump is an upgraded oil pump designed for Honda H22 engines. This pump addresses common issues with the stock H22 oil pump, such as cavitation and pressure loss at high RPMs and elevated oil temperatures, particularly in endurance applications.

It starts with a new OEM Honda oil pump, which is then disassembled to port and smooth the oil passages, increasing flow. The pumps are meticulously cleaned, oiled, reassembled, and repackaged.
