FAQ
Are these suitable for a daily-driven stock turbo?Not recommended. 150% over injectors typically require upgraded air, fuel supply, and custom calibration for street manners.
Do I need new injector feed tubes?Highly recommended—worn tubes can cause sealing issues and poor injector performance. See our feed/connecting tube options above.
What’s special about S&S SAC nozzles and matching?S&S uses SAC nozzles with proprietary honing, then flow-matches and profiles the set for consistent delivery across all six cylinders.
