Fuel Injector Clinic Four Cylinder 445cc Custom Injector Set - 64mm Height - 11mm Top O-Ring Diameter - 21mm Bottom O-Ring Diameter (Product Code: 0445-64-11-21-4) - ISC-0445H-4
The Fuel Injector Clinic 445cc Custom Injector Set is engineered for four-cylinder performance applications that demand reliable fuel delivery, excellent drivability, and precise tuning characteristics. Featuring a 64mm injector height, 11mm top O-ring diameter, and 21mm bottom O-ring diameter, this custom high impedance injector set delivers the consistent fueling needed for naturally aspirated, turbocharged, and supercharged combinations. Outstanding short pulse width control and tight manufacturing tolerances provide smooth idle quality, crisp throttle response, and predictable tuning results.
Every injector is individually numbered and precision flow matched to within 1% to ensure consistent cylinder-to-cylinder fuel delivery. Each set is flow tested at 43.5 PSI (3 Bar) at 90 degrees F using CF-16B calibration fluid and includes solder-in pigtails, the correct O-rings for the specified dimensions, and a detailed flow sheet documenting each injector's performance. Backed by Fuel Injector Clinic's lifetime warranty against manufacturing defects, this injector set delivers the quality and confidence serious enthusiasts expect.
