Shop with Blessed Performance for the Exergy Performance Sportsman Fuel Injectors (Set of 8) for your 2001-2004 GM 6.6L LB7 Duramax diesel. At 10% over stock, these are an affordable upgrade for stock trucks and people looking for a slight increase in performance without worrying about smoke or heat issues. No other vehicle modifications are required. The nozzles are enlarged using abrasive flow honing technology and are hydraulically flow matched to less than 1%. Each nozzle undergoes four separate quality control checks throughout the process before being installed back onto the injector. All factory nozzle LB7 injectors are equipped with the latest DLC coated needle design to increase longevity. All components are built and tested on specialized equipment designed and built in-house at Exergy. Every Sportsman injector set is tested at multiple calibration points, balanced to +/- 1%, and shipped with a detailed calibration sheet. Injector seal kit included (copper gaskets and o-rings).
Note: These injectors can be used as a direct replacement for Bosch part numbers 0 445 120 008 and 0 986 435 502, as well as GM Part numbers 97729095, 97720661, and 97208074.
