Precision Flow Matching & Testing
Every Fuel Injector Clinic injector set is flow matched to within 1% to ensure balanced cylinder fueling and smooth engine operation. Each injector is:
-
Individually numbered
-
Flow tested and documented
-
Supplied with a detailed flow data sheet
Injectors are tested at 43.5 psi (3 bar) and 90°F fuel temperature using CF-16B calibration fluid, providing accurate and repeatable real-world performance data.
Advanced Injector Technology
These injectors utilize the latest internal injector technology to deliver:
-
Excellent linearity across the entire flow range
-
Superior short pulse-width control
-
Consistent idle quality and part-throttle drivability
-
Easier tuning compared to lower-quality or remanufactured injectors
Tight manufacturing tolerances and advanced design make these injectors well-suited for both street and performance applications.
Installation & Fitment
-
Includes all required O-rings for direct fitment on factory LS1 fuel rails
-
Injector plug conversion required
-
Included: Pigtails (PGTUSC8) for solder-in installation
-
