The DDP 8993-ECO Economy Series is a brand-new set of 6 injectors for 1989-1993 Dodge Ram trucks with the 5.9L 12-valve Cummins. Each injector uses a new body and a new SAC nozzle, not a remanufactured core.

It is built for stock or lightly modified trucks that need fresh injectors and a slight gain over factory. Pilot hole nozzles cut idle haze and sharpen throttle response for smooth daily driving.

• All-New Construction: New injector bodies and nozzles, no reman cores.
• Slight Gain Over Stock: A modest bump for stock or lightly modified trucks.
• Pilot Hole Technology: Two 0.005 inch pilot holes reduce idle haze.
• Balanced Set of 6: Even fueling from cylinder to cylinder.
• Copper Washers Included: 1.5 mm washers come with the set.

Vehicle Fitment & Technical Installation Notes

• Installation Tip: Non-intercooled heads have a 9 mm nozzle bore. DDP recommends the included 1.5 mm copper washer instead of a 9 mm adapter sleeve, since it sets the nozzle tip closer to the piston for a cleaner burn.
