The Fuel Injector Clinic 775cc Custom Injector Set is designed for four-cylinder performance applications requiring a 53mm injector height while delivering exceptional fuel control and dependable drivability. Featuring a 53mm injector height, 14mm top O-ring diameter, and 21mm bottom O-ring diameter, these high impedance injectors are an excellent solution for naturally aspirated, turbocharged, and supercharged engine combinations. Superior short pulse width control delivers smooth idle characteristics, crisp throttle response, and predictable ECU tuning from daily driving to dedicated motorsports applications.
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 comprehensive 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 along with the correct O-rings for the specified dimensions. Every Fuel Injector Clinic injector is backed by a lifetime warranty against manufacturing defects.
