Fuel Injector Clinic 1440cc High Impedance Fuel Injector Set for LS1 Engines (IS301-1440H)
Unlock the fueling capacity needed for serious naturally aspirated, boosted, or E85-powered LS builds with the Fuel Injector Clinic IS301-1440H High Impedance Fuel Injector Set. Designed for LS1 engines, this set of eight injectors flows 1440cc/min (140 lb/hr) at 43.5 PSI (3 Bar) and an impressive 160 lb/hr (1700cc/min) at the factory 58 PSI (4 Bar) fuel pressure. Positioned between Fuel Injector Clinic's proven 1200cc and 1650cc injectors, the IS301-1440H delivers the ideal balance of excellent street manners and the fuel volume required for high-horsepower gasoline and E85 combinations.
Built using the latest high impedance injector technology, the IS301-1440H features exceptional linearity, superior short pulse width repeatability, and Fuel Injector Clinic's industry-leading Data Match Technology. Every injector is individually serial numbered and dynamically matched, with a detailed Data Match Sheet included to provide injector-specific flow and latency values for precise ECU calibration. This injector set includes USCAR injector pigtails (PGTUSC8), while optional Plug and Play adapter harnesses (PADPUtoJ8) are available separately for installations that require no cutting or soldering. Fuel Injector Clinic also provides Plug and Play GM ECU data for simplified tuning.
Thanks to its durable stainless alloy valve construction, the IS301-1440H is compatible with virtually every popular performance fuel, including pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. Like every Fuel Injector Clinic performance injector, these are brand-new injectors rather than remanufactured cores, providing maximum reliability for demanding street and race applications.

FAQs
What makes the IS301-1440H different from the 1200cc and 1650cc injector sets?
The IS301-1440H fills the gap between Fuel Injector Clinic's 1200cc and 1650cc injectors, offering additional fuel capacity while maintaining excellent idle quality and drivability. It is an ideal choice for high-horsepower street and race applications that need more flow without stepping up to the larger 1650cc injector.
Can these injectors be used with E85 and race fuels?
Yes. The stainless alloy valve construction allows the IS301-1440H to operate with pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels while maintaining excellent performance and durability.
