Fuel Injector Clinic 1440cc High Impedance Fuel Injector Set for 1983-1986 Buick Regal T-Type & 1984-1987 Buick Grand National (IS309-1440H)
Step up to serious fueling performance with the Fuel Injector Clinic IS309-1440H 1440cc High Impedance Fuel Injector Set. Designed specifically for the legendary Buick Regal T-Type and Grand National, this matched set of six top-feed injectors delivers the fuel capacity needed for high-horsepower street and race builds while maintaining the exceptional idle quality and drivability that Fuel Injector Clinic injectors are known for. Positioned between FIC's popular 1200cc and 1650cc injectors, the 1440cc injector offers an outstanding balance of street manners and substantial fuel delivery for demanding gasoline and E85 combinations.
Built using the latest high impedance ball and seat injector technology, the IS309-1440H features outstanding linearity, excellent short pulse width repeatability, and Fuel Injector Clinic's proprietary 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 highly accurate ECU tuning. This injector set includes USCAR injector pigtails (PGTUSC6), while optional Plug and Play adapter harnesses (PADPUtoJ6) are available separately for installations that require no cutting or soldering.
The 1440cc high impedance injector is compatible with virtually every popular performance fuel thanks to its stainless alloy valve construction. It is fully compatible with pump gasoline, E85, Q16, VP Import, FTW, MTBE oxygenated race fuels, and other racing fuels while still offering excellent idle quality for street-driven vehicles. As with every Fuel Injector Clinic performance injector, these are brand-new injectors, never remanufactured cores, ensuring maximum reliability and long service life.

FAQs
What makes the 1440cc injector different from the 1200cc and 1650cc versions?
The IS309-1440H fills the gap between Fuel Injector Clinic's 1200cc and 1650cc injectors, providing additional fuel capacity while maintaining excellent idle quality and drivability. It is an excellent choice for high-horsepower street and race applications that require more fuel than a 1200cc injector but do not need the capacity of a 1650cc injector.
Can these injectors be used with E85 and race fuels?
Yes. The stainless alloy valve construction allows the IS309-1440H to operate with pump gasoline, E85, Q16, VP Import, FTW, MTBE oxygenated race fuels, and virtually all commonly used performance fuels.
