Frequently Asked Questions:
Do I need a core for NEW injectors?Many dealers list a refundable core charge on late-5.9 S&S injector sets (NEW and reman) to ensure return logistics; check your cart for the current core policy.
What supporting mods are recommended?
At minimum, pair with a healthy CP3 pump, quality lift pump/filtration, and fresh connector/feed tubes to protect injectors and maintain rail pressure.
How are S&S injectors built and matched?
S&S late-5.9 injectors use SAC nozzles, proprietary honing, and are flow-matched per set to tight tolerances under OE-style test conditions for consistent rate shaping and delivery.
Can my stock turbo and tuning handle 80% over?
You’ll need appropriate air (turbo setup) and tuning to manage EGT and smoke. Consider staged upgrades and consult your tuner for pulse-width and rail pressure strategy suitable for 80% over injectors.
