FAQ
What does “100% over” mean for L5P injectors?It denotes approximately double the stock nozzle flow. S&S sizes and matches nozzles/injectors to strict tolerances and aligns rate-shape for consistent cylinder delivery.
Do I need tuning with 100% over injectors?Yes. Proper calibration is required to realize the benefit of increased flow and to maintain drivability and control.
Are these built from new or reman cores?They are built from new L5P injectors that S&S modifies in-house, then flow-matches as a complete set.
Are these street legal?High-flow L5P injectors are competition-oriented. Verify emissions compliance for your intended use and location.
