Description

The Genuine Mazda oil injectors are brand new, direct replacement parts for the RX-7 FD3s. These components are critical for the proper functioning of the 13b REW engine, as they deliver oil to the combustion chamber for seal lubrication. These oil injectors are a common point of failure on the RX-7 FD3s. When they fail, they will no longer hold vacuum, which can lead to lubrication issues and potential engine damage. Each 3rd generation 13b REW engine is designed to use two of these injectors. It is recommended to replace these injectors in pairs to ensure consistent performance and optimal engine health. Proper installation is essential, and consulting a service manual or a qualified rotary engine specialist is advised.
