Fuel Injector Clinic Four Cylinder 540cc SHORT Custom Injector Set - 38mm Height - 11mm Top O-Ring Diameter - 14mm Bottom O-Ring Diameter (Product Code: 0540-38-11-14-4) - ISC-0540H-4
The Fuel Injector Clinic 540cc SHORT Custom Injector Set is engineered for four-cylinder performance applications requiring compact 38mm shorty injectors without sacrificing fuel delivery or drivability. Featuring a 38mm injector height, 11mm top O-ring diameter, and 14mm bottom O-ring diameter, this custom high impedance injector set delivers precise fueling for naturally aspirated, turbocharged, and supercharged engine combinations where space is limited. Superior short pulse width control and tight manufacturing tolerances provide smooth idle quality, crisp throttle response, and predictable ECU calibration.
Every injector is individually numbered and precision flow matched to within 1% for exceptional cylinder-to-cylinder consistency. Each injector 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 the performance of every injector. Fuel Injector Clinic backs every injector against manufacturing defects with a lifetime warranty for long-term confidence in your fuel system.
