Recommended Supporting Parts
100% over injectors demand proper fuel supply and high-pressure capability. We recommend pairing with:
- 03–07 Cummins CP3 Injection Pumps (stock to high-performance)
- 03–07 Cummins Fuel System Components (big line kits, rails/sensors, filtration)
- 03–07 Cummins Lift Pumps (supply pressure & filtration for CP3 longevity)
- Shop All Exergy Injectors (browse flow levels and related sets)
Install Notes
- Professional installation recommended. Always replace sealing washers and torque to spec.
- Prime/bleed the fuel system thoroughly; verify no return-line restrictions.
- Match air (turbo) and high-pressure supply (CP3) to fueling; tuning is required for safe EGT and rail control.
Frequently Asked Questions
Q: Are these new or reman?
A: These are brand-new Exergy injectors, sold as a flow-matched set.
Q: Do I need a larger CP3 and a lift pump?
A: For 100% over, a quality lift pump and an upgraded CP3 are strongly recommended to maintain commanded rail pressure under load.
Q: Is tuning required?
A: Yes. Calibrations are required to control rail pressure, manage smoke/EGT, and extract the intended power safely.
Q: Will these work on 2004.5–2007?
A: No—this set is for early CR (2003–2004). Late CR (2004.5–2007) uses different part numbers—see Exergy late-CR listings.
Q: Warranty?
A: Covered by Exergy’s manufacturer warranty; use clean fuel and follow proper install/filtration practices.
