Corvette Engine Build - The Power Principal, Part 2 Photo Gallery
Our Bosch EV1 fuel injector is at the top of the photo. Although the external features of these injectors look similar, that's where it ends. Bosch stamps their build number on the upper injector body. This number correlates to fuel delivery and injector design. The clone injector has a painted number on the lower steel case with no stamping on the plastic upper body.
