Frequently Asked Questions

Do I need tuning to install these injectors?

No tuning is required if you are installing these injectors into a vehicle originally equipped with 12580681 part number injectors. These are stock OEM flow rate injectors and direct replacements for compatible GM vehicles listed in the compatibility.
