Dodge Ram Cummins 1989-1993 First Gen 12 5.9L Valve Injector Set: With proper supporting modifications injectors will support up to 275 RWHP. Sold as a Brand New matched set. Excellent mileage and smoke control. No core.

Note: VE Rotary injection pump should have an upgraded fuel pin installed or little to no gain will be seen from injector upgrade. Our part number for the upgraded fuel pin is: DDP PIN

Pilot Hole Technology - These injectors use a 5 Hole + 2 Pilot nozzle.  Pilot holes allow the fuel to come in gradually to help with spool time without having to have a ton of extra smoke

245 BAR Pop Pressure

NON-INTERCOOLED ENGINE FITMENT NOTE: Non-Intercooled engines come from the factory with a 9mm diameter injector nozzle bore in the cylinder head.  All Dynomite Diesel injectors for this application come with a 7mm diameter injector nozzle along with a standard 1.5mm thick copper washer.  Many manufacturers supply a copper sleeve to adapt the 7mm diameter injector nozzle to the 9mm diameter bore in the Non-Intercooled cylinder head but this is not needed.  At Dynomite we've been running the standard copper washer with a Non-Intercooled cylinder head for over 20 years now with zero issues.  We actually prefer the standard 1.5mm copper washer as compared to the adapter sleeve as it is 0.5mm thinner than the copper sleeve adapter and physically moves the tip of the nozzle closer to the piston resulting in a cleaner burn with improved fuel economy and power output.  If you still want to run the copper sleeve adapter you can but they are not recommended by Dynomite.  9mm Adapter Sleeve is Cummins PN: 3919358
