FAQ
Do I need tuning for 45% over injectors on a 6.4L?Yes—plan for proper calibration so commanded rail pressure, pulse width, and air/fuel stay in a safe window. Stock tunes are not optimized for 45% flow.

Yes. This is a NEW set of 8 S&S 6.4F-45SAC injectors, matched to S&S standards for consistent rate shape and flow.
What’s the nozzle type and size?
SAC-style nozzles, 45% over compared to stock—ideal for clean, controllable power gains with supporting mods.
What supporting mods are recommended?
At minimum: fresh filters, a healthy lift pump/supply, and monitoring. For higher power, consider head studs and upgraded air system components.
Is there a core charge?
Yes. 6.4L Ford sets require a core return; if no core is returned, a fee is typically assessed. Your CPP invoice will include the current core details.
