Stage One Injectors

The Classic Diesel Design's stage one injectors use a G code nozzle, hand finished for a quality spray pattern and custom pop pressure spec designed to get the most out of your performance injection pump while retaining a smooth idle and crisp injection event. These injectors have been proven to be a great match for stock to wild injection pumps, with noticeable performance gains over a stock injector beyond 100cc with modified injection pumps.
