Fuel Injector Clinic Four Cylinder 1650cc Custom Injector Set - 53mm Height - 11mm Top O-Ring Diameter - 15mm 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 53mm injector height, 11mm top O-ring diameter, and 15mm 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 applications that demand exceptional fuel delivery while maintaining excellent idle quality and smooth drivability when professionally tuned.
Each injector is individually serial numbered and precisely matched using Fuel Injector Clinic's proprietary Data Match Technology, providing industry-leading cylinder-to-cylinder consistency along with detailed latency data for more accurate ECU calibration. Every custom injector set includes solder-in pigtails, the required O-rings for the specified dimensions, and a comprehensive Data Match Sheet. Each 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.
