FAQ
Are these truly 60% over stock?Yes. The “60%” refers to the increase in nozzle flow vs. stock. S&S sizes and calibrates sets to keep flow variance tight for drivability.
What’s the difference between SAC and VCO nozzles?SAC nozzles use a sac volume behind the holes, favored in performance applications for durability and consistent flow characteristics.
Do I need tuning and other supporting mods?For best results with 60% over injectors, plan on proper ECM calibration plus adequate lift pump, filtration, and turbo/exhaust flow to match your power goals.
Are these new or reman?This specific part number (LMM-60SAC-R-SET) is a remanufactured set; S&S also offers new-body options on other SKUs and sizes.
