Fuel Injector Clinic Four Cylinder 1440cc Custom Injector Set - 53mm Height - 11mm Top O-Ring Diameter - 14mm Bottom O-Ring Diameter (ISC-1440H-4)
The Fuel Injector Clinic Four Cylinder 1440cc Custom Injector Set is built for custom four-cylinder fuel systems requiring a 53mm injector height, 11mm top O-ring diameter, and 14mm bottom O-ring diameter. Delivering 1440cc/min of fuel flow, these high impedance injectors fit between Fuel Injector Clinic's 1200cc and 1650cc offerings, providing the fuel capacity needed for serious horsepower while maintaining excellent idle performance and street-friendly drivability.
Stainless alloy valve construction allows these injectors to be used with pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. Each set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology, individually serial numbered, and supplied with a Data Match Sheet containing detailed flow-matching and latency information. Custom injector sets also include solder-in pigtails for integration into the vehicle's wiring system.
