Helpful Notes
- 150% over injectors demand adequate air (appropriate turbo/turbos) and fuel supply (healthy CP3 and lift pump). Expect tuning and supporting mods.
- Always use new connector/feed tubes and the correct install kit for your model year to avoid sealing/contamination issues.
- Professional installation and injector quantity verification (balance rates) recommended.
Yes — these are for the late 5.9L CR (2004.5–2007, 325 HP rating). Early 2003–early-2004 (305 HP) use the early-style set.
What supporting mods are required for 150% over injectors?
At minimum: upgraded turbo(s), lift pump, a healthy CP3 with adequate displacement, and proper tuning. Stock air/fuel systems cannot support this injector size.
Is there a core charge on this NEW set?
S&S notes a $150 core charge if no core is returned across late 5.9 injector sets. Retailers may implement their own core policies; check your cart at checkout.
Are these flow-matched as a set?
Yes. Nozzles are matched to ~1% and injectors to ~3% using OE-standard test fluids and multi-point calibration for consistent rate shape.
