FAQ — Are these truly “30% over,” and what does that mean?
“30% over” refers to the nozzle flow increase vs. stock. S&S sizes injectors by percentage over stock nozzle flow and then builds the injector to match that nozzle so rate shape and control are maintained.
FAQ — Do I need tuning or other upgrades?
While not strictly required, 30% over injectors benefit from proper tuning and healthy supply pressure. Pair with a quality lift pump and ensure filtration is up to spec to protect your investment.
FAQ — Is there a core charge?
Yes. S&S requires core returns on 6.4L Ford injectors and assesses a charge if cores are not returned. Please plan to return usable cores to avoid fees.
FAQ — What is SAC vs. VCO and why does it matter?
SAC (sac-type) nozzles are favored for durability and consistency in high-output use compared to VCO. S&S provides technical content comparing the two and outlining the benefits of modern SAC designs.
