Product Description
S&S Diesel 6.4F-100SAC-SET is a 100% over, flow-matched SAC-nozzle injector set (8) engineered for the demands of built 2008–2010 6.4L Powerstroke trucks. Each injector is matched to S&S’s nozzle flow and test standards for consistent delivery across the set.
Fitment
- 2008–2010 Ford F-250 / F-350 / F-450 Super Duty — 6.4L Powerstroke (Set of 8 injectors)
Why S&S
- Proprietary nozzle honing for clean, consistent orifice geometry
- Nozzles flow-matched to ~1% per set; injectors flow-matched to ~3% per set on OE-standard equipment
- Injection profiles aligned; build spec matched to nozzle flow (includes internal piezo modifications for 6.4L)
What’s Included
- (8) S&S Diesel 100% over SAC-nozzle injectors for 6.4L Powerstroke
- Flow data sheet / set matching per S&S process
- Core return instructions (core required for 6.4L sets)
Recommended Parts
- S&S Diesel — brand catalog
- AirDog Lift Pump Kits — ensure adequate supply for high-flow injectors
- Fuel Filter Service Kits — protect new injectors with fresh filtration
- 6.4L Fuel System Components — rails, lines, and accessories
- 6.4L Custom Tuning & Programmers — calibrate for 100% over injectors
- Injector Install Gaskets & Seals — 6.4L
Helpful Notes
- 100% over nozzle flow is a sizing convention; actual fuel output also depends on rail pressure and injection duration.
- High-flow injectors require sufficient lift pump capacity and appropriate calibration.
FAQs
Do I need custom tuning with 100% over injectors?Yes. To realize safe power gains and proper drivability, custom calibration is highly recommended for 100% over sizing on the 6.4L.
Are these new or reman?S&S builds injectors using brand-new or Bosch reman bodies depending on availability, then matches and tests them as a set to their standards.
Is there a core charge?Yes. Core returns are required on 6.4L Ford injectors; a core charge applies if no core is returned.
What’s the difference between 100% over and 30/60/80%?The percentage refers to nozzle flow increase relative to stock. It’s a sizing guide; real fueling change varies with pressure and duration.
Will stock fuel supply components support 100% over?Usually not. Upgrade the lift pump and ensure filtration is fresh to protect and feed the injectors appropriately.
