Product Description
Sharpen your LBZ’s fueling with precision. Industrial Injection’s Dragonfly extrude-honed nozzle delivers ~23 LPM flow (about +15%) for clean atomization, quicker spool, and lower EGT potential when properly calibrated. Perfect match for a mild street/tow tune or as a stepping stone in a larger build.

FAQ
Is this sold individually or as a set?This Dragonfly LBZ nozzle is sold individually. Order quantity 8 for a full engine set.
Do I need tuning with this nozzle?Yes. Even with modest flow increase (~23 LPM), proper ECM calibration is recommended for rail control, smoke management, and EGTs.
What power can 23 LPM support?With healthy hardware and a good tune, many LBZ builds see around +50 HP from nozzles alone; results vary by turbo, altitude, and fuel quality.
What else should I upgrade?A quality lift pump and CP3 health/volume are key. For bigger goals, consider a CP3 internal upgrade or twin CP3s.
Notes
- Competition-use only where required; check local/state emissions laws.
- Professional installation and injector balancing procedures are recommended.
