The DDP 8993-1 Stage 1 injector set is a brand-new, matched set of 6 injectors for 1989-1993 Dodge Ram trucks with the 5.9L 12-valve Cummins. Dynomite Diesel rates it at about 50 HP over stock, and it can support up to 275 RWHP with the right supporting parts.

Patented pilot hole nozzles bring fuel in gradually, so the turbo spools faster without heavy smoke. It is a good first step for a daily driver or tow rig that needs more power and still has to behave on the street.

• About 50 HP Over Stock: A noticeable gain without going to an aggressive set.
• Pilot Hole Technology: Two 0.005 inch pilot holes help spool the turbo with less smoke.
• SAC Nozzles: Fine spray for better atomization and fuel economy.
• New Matched Set: Six brand-new, balanced injectors for even fueling.
• Copper Washers Included: 1.5 mm washers come with the set.

Vehicle Fitment & Technical Installation Notes

• Fitment: 1989-1993 Dodge Ram 250/350 (D250, D350, W250, W350) with the 5.9L 12V Cummins and VE rotary pump. 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.
• Installation Tip: Install an upgraded fuel pin in the VE pump. Without it you will see little to no gain from the injectors.
