4Piston Racing Ported D-series Oil Pump
4Piston Racing Ported D-series Oil Pump
The stock oil pump is a great piece for up to 7,000 rpm. Past that, there can be cavitation issues and oil pressure drops as temperatures rise. 4Piston Racing's ported pump increases flow by 25% and will allow continuous use above 9,000 rpm. 4Piston starts with a brand new OEM oil pump from Honda, disassemble, port and smooth oil passages to increase flow. The pumps are then cleaned, oiled, reassembled and repackaged. This part is cheap insurance to protect your multi-thousand dollar investment.
