Fuel Injector Clinic Four Cylinder 650cc Custom Injector Set - 53mm Height - 11mm Top O-Ring Diameter - 16mm Bottom O-Ring Diameter (Product Code: 0650-53-11-16-4) - ISC-0650H-4
The Fuel Injector Clinic 650cc Custom Injector Set is engineered for four-cylinder performance applications requiring a 53mm injector height while delivering exceptional fuel control and drivability. Featuring a 53mm injector height, 11mm top O-ring diameter, and 16mm bottom O-ring diameter, this high impedance injector set is an excellent choice for naturally aspirated, turbocharged, and supercharged engine combinations. Superior short pulse width control and advanced matching technology provide crisp throttle response, stable idle quality, and predictable ECU tuning.
This injector set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Every injector is individually serial numbered and supplied with a Data Match Sheet containing detailed flow matching and latency information for each injector. 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 and the correct O-rings for the specified dimensions. Every Fuel Injector Clinic injector is backed by a lifetime warranty against manufacturing defects.
