4PistonRacing upgrade oil pump (D16Z/D16Y engines)
Description
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. Our ported pump increases flow by 25% and will allow continuous use above 9,000 rpm. We start 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.
Please mention in the check out (in the request field) the engine type you have/need (D16Z or D16Y)
