Description

The DragonFly is a reman 60HP / 13% over injector for the 2003-2004 5.9L Common Rail Cummins, extrude-honed and flow-balanced to 27 LPM. Built in-house on brand-new factory OEM parts (including the nozzles), with tighter tolerances than the original manufacturer's spec.

Works well on a fully stock truck or one running tuning and turbo upgrades. Sold individually — order a full set of six and have them installed as a matched set.

Features

• 60HP gain / 27 LPM / 13% over stock
• Extrude-honed and flow-balanced to tight tolerance
• Built with new factory OEM parts including nozzles
• Direct OEM-replacement design
• Includes new copper crush washer and O-rings for installation
• Individually tested: resistance, system leak, purge, idle, mid-load, full-load, static back-leak

Notes

• When replacing injectors on the 5.9L Common Rail, replace the injector connecting tubes at the same time — tube contamination is the most common cause of new-injector failure.
• Core deposit applies — keep your old injectors and return them to recover the deposit.
