Fuel Injector Clinic Four Cylinder 1650cc Custom Injector Set - 64mm Height - 14mm Top O-Ring Diameter - 14mm Bottom O-Ring Diameter (ISC-1650H-4)
The Fuel Injector Clinic 1650cc Custom Injector Set is engineered for custom four-cylinder performance applications requiring a 64mm injector height, 14mm top O-ring diameter, and 14mm bottom O-ring diameter. Delivering 1650cc/min of fuel flow, these high impedance injectors are built for high-horsepower street, drag racing, road racing, and dedicated competition vehicles that demand exceptional fueling capacity while maintaining excellent idle quality and smooth drivability when properly calibrated.
Every injector is individually serial numbered and precisely matched using Fuel Injector Clinic's proprietary Data Match Technology, providing exceptional cylinder-to-cylinder consistency and detailed latency data for more accurate ECU calibration. Each custom injector set includes solder-in pigtails, the required O-rings for the specified dimensions, and a comprehensive Data Match Sheet. Every injector is flow tested at 43.5 PSI (3 Bar) at 90 degrees F using CF-16B calibration fluid and is backed by Fuel Injector Clinic's lifetime warranty against manufacturing defects.
