The S&S Diesel 40% Over Reman Injector Set is designed for 2003-2004 5.9L Cummins. It adds a moderate increase in fuel delivery for responsive street and towing performance. This remanufactured set of 6 is intended for modified 5.9L Cummins trucks that need more fuel without moving to an extreme competition-size injector.
