Frequently Asked Questions
Q: Are these true 200% “over” injectors?
A: Yes—Exergy calibrates and balances these to flow ~200% over stock for the 03–04 5.9L CR platform.
Q: Do I need a bigger CP3?
A: Yes. For 200% over nozzles you should pair with a high-output CP3 such as the Exergy Sportsman CP3, or step up to stroker options depending on power goals.
Q: Is custom tuning required?
A: Absolutely. With 200% overs, tuning is mandatory to control smoke, EGT, driveability, and rail pressure.
Q: Street legal?
A: These are intended for off-road/competition use where emissions compliance is not required. Check local laws.
Q: Can I buy single injectors?
A: This listing is for a matched set of 6. If you need singles, contact us for availability.
