Show original supplier description
The Fuel Injector Clinic IS303-1440H is a set of eight high-impedance fuel injectors engineered for enhanced performance. These injectors provide a flow rate of 1440cc/min (160 lbs/hr) at a standard 58 PSI fuel pressure, and 1700cc/min (160 lbs/hr) at 4 bar (58 PSI) fuel pressure. They are compatible with a wide range of fuels, including pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels, thanks to their stainless alloy valve construction. They utilize the latest injector technology and come precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Each injector is individually serial numbered, with results provided on a Data Match Sheet for complete flow matching and latency value information. This ensures superior short pulse width control and excellent drivability, making them easy to tune. FIC injectors are flow tested and rated at 43.5psi (3Bar) at 90deg F fuel temperature using CF-16B calibration fluid. The IS303-1440H set is compatible with GM LS3, LS7, LSA, L76, L92, and L99 engines. For aftermarket or unusual setups, contacting Fuel Injector Clinic prior to ordering is recommended to ensure proper fitment. All Fuel Injector Clinic injectors are covered by a lifetime warranty against failures caused by manufacturing defects.
