FAQ
What does “450% over” mean?It refers to approximate nozzle flow increase versus stock. S&S sizes injectors by percentage over stock and pairs nozzles with matched bodies to keep delivery consistent across the set.
Are these street legal?At 450% over, these are typically used for off-road/competition builds. Confirm local regulations before ordering and installing.
Do I need new feed tubes?Replacing feed tubes during injector service is recommended to ensure sealing and performance. See our 03–04 category for feed tube options.
Are the injectors matched?Yes. S&S notes nozzles are matched to 1% per set and injectors to ~3% with multiple test points, promoting smooth operation across cylinders.
