FAQ
Are these true 250% over injectors and flow-matched as a set?Yes. S&S sizes by percent-over stock and flow-matches injectors and nozzles using OE-standard methods; 250% and up include internal body mods.
Do I need tuning and supporting fuel/air mods?Absolutely. At 250% over, you should plan for significant air upgrades, lift pump capacity, and CP3 supply, plus professional tuning for drivability and reliability.
Will these fit any 2004 model year truck?They fit Late 2004.5–2007 trucks. If you have an early-2004 engine, verify your engine build tag for the correct injector family.
Is there a core charge?Yes—S&S indicates core returns are required on Late 5.9 injectors; check your order confirmation for the exact core details.
