Fuel Injector Clinic Four Cylinder 1440cc Custom Injector Set - 53mm Height - 11mm Top O-Ring Diameter - 21mm Bottom O-Ring Diameter (ISC-1440H-4)
The Fuel Injector Clinic 1440cc Custom Injector Set is engineered for custom four-cylinder fuel systems requiring a 53mm injector height, 11mm top O-ring diameter, and 21mm bottom O-ring diameter. Delivering 1440cc/min of fuel flow, these high impedance injectors bridge the gap between Fuel Injector Clinic's 1200cc and 1650cc injector offerings, making them an excellent choice for high-horsepower street, drag racing, road racing, and dedicated competition vehicles that require exceptional fuel delivery without sacrificing idle quality or drivability.
Featuring a stainless alloy valve, these injectors are compatible with pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. Every injector is individually serial numbered and precisely matched using Fuel Injector Clinic's exclusive Data Match Technology, providing industry-leading cylinder-to-cylinder consistency and comprehensive latency data. Each custom injector set includes solder-in pigtails, the required O-rings for the specified dimensions, and a detailed Data Match Sheet. Fuel Injector Clinic backs every injector against manufacturing defects with a lifetime warranty for long-term confidence.
