Important Requirements & Notes

These injectors are designed for high-performance / competition builds. Modified or dual CP3 fuel systems, upgraded turbo(s), and custom tuning are mandatory. They are not recommended for daily-driven street applications.

LB7 Injector Line Note: The factory fuel injector lines on the LB7 are known to rust and can damage new injectors. We strongly recommend replacing the injector lines if they have not been changed within the last 40,000–50,000 miles.

Perfect for serious LB7 builds looking for maximum fueling capability in a reliable, brand-new matched set from Dynomite Diesel.
