Fuel Injector Clinic 1000cc High Impedance Fuel Injector Set for 1983-1986 Buick Regal T-Type & 1984-1987 Buick Grand National (IS309-1000H)
Upgrade the fuel system in your turbocharged Buick with the Fuel Injector Clinic IS309-1000H 1000cc High Impedance Fuel Injector Set. Designed specifically for the iconic Buick Regal T-Type and Grand National, this matched set of six top-feed injectors provides the fuel capacity needed for high-performance gasoline and E85 combinations while maintaining the excellent drivability, throttle response, and idle quality Fuel Injector Clinic injectors are known for. Whether you're building a powerful street car or a competitive drag car, these injectors deliver the consistency and precision your combination demands.
Utilizing advanced high impedance ball and seat injector technology, the IS309-1000H offers exceptional linearity and superior short pulse width repeatability, making tuning easier across the entire operating range. Every injector is individually serial numbered and precisely matched using Fuel Injector Clinic's proprietary Data Match Technology, with each set including a detailed Data Match Sheet containing injector-specific flow and latency values for highly accurate ECU calibration. This kit includes USCAR injector pigtails (PGTUSC6), while optional Plug and Play adapter harnesses (PADPUtoJ6) are available separately for installations that require no cutting or soldering.
Fuel Injector Clinic utilizes brand-new injectors instead of remanufactured or core-based units, providing greater long-term reliability and eliminating the potential issues commonly associated with rebuilt injectors. Because these injectors use a different connector style than the factory wiring harness, either the included pigtails or optional adapter harnesses must be used during installation.

FAQs
Do these injectors plug directly into the factory wiring harness?
No. The IS309-1000H uses brand-new injectors with a different connector than the factory harness. The included USCAR pigtails can be soldered into your harness, or optional PADPUtoJ6 Plug and Play adapter harnesses can be purchased for a no-cut installation.
Why does Fuel Injector Clinic use new injectors instead of remanufactured cores?
Fuel Injector Clinic believes brand-new injectors provide greater long-term reliability and eliminate the potential failures associated with rebuilt or core-based injectors, making them a better solution for high-performance applications.
