Helpful Notes
- Tuning & Airflow Required: 80% over injectors move significantly more fuel and require proper tuning and sufficient turbo/airflow to avoid excessive EGT and smoke.
- Fuel Supply: Upgrade lift pump and filtration to protect injectors and maintain rail pressure under load.
- Line/Tube Best Practice: Replace high-pressure lines and feed tubes during installation to ensure proper sealing.
FAQ: Will these 80% over injectors work on my 2005 5.9L?
No. This is the early 5.9L set for 2003–2004 (early 2004) trucks. 2004.5–2007 “late” trucks need the late-style injectors.
FAQ: Do I have to replace feed tubes and injector lines?It’s strongly recommended. New feed tubes and, if removed, new high-pressure lines help ensure proper sealing and long-term reliability.
FAQ: What supporting mods are required for 80% over?At minimum: adequate turbo/airflow upgrades, proper ECU calibration, and a healthy CP3 (often stroker or dual CP3 for big power) plus a quality lift pump and filtration.
FAQ: Are these brand-new or reman?This listing is for a brand-new set of six. S&S also offers reman sets for early 5.9L under different part numbers.
