Fuel Injector Clinic 2150cc High Impedance Fuel Injector Set for 1983-1986 Buick Regal T-Type & 1984-1987 Buick Grand National (IS309-2150H)
Built for the most demanding turbo Buick combinations, the Fuel Injector Clinic IS309-2150H 2150cc High Impedance Fuel Injector Set delivers incredible fuel capacity without sacrificing the drivability serious enthusiasts expect. Designed specifically for the legendary Buick Regal T-Type and Grand National, this matched set of six injectors utilizes the latest high-performance injector technology along with Fuel Injector Clinic's proprietary Data Match Technology to provide outstanding idle quality, exceptional low pulse width control, and precise fuel delivery for extreme horsepower builds.
Unlike many ultra-high-flow injectors, the IS309-2150H is dynamically matched during production to improve ECU control in the critical sub-2 millisecond pulse width range commonly encountered at idle and part throttle. Every injector is individually serial numbered and includes a detailed Data Match Sheet with injector-specific flow and latency values, allowing tuners to achieve highly accurate calibration and excellent cylinder-to-cylinder consistency. This injector set includes Denso injector pigtails (PGTDEN6), while optional Plug and Play adapter harnesses (PADPDtoJ6) are available separately for installations that require no wiring modifications.
The IS309-2150H is an outstanding solution for extreme horsepower gasoline and E85 applications. However, because of the injector's internal seal design, these injectors must NOT be used with MTBE oxygenated fuels such as VP Import or Q16. Fuel Injector Clinic also recommends following proper maintenance procedures when using alcohol-based fuels to minimize the potential for corrosion during extended storage.

FAQs
Can I use these injectors with VP Import or Q16 race fuel?
No. Fuel Injector Clinic specifically advises against using the IS309-2150H with MTBE oxygenated fuels such as VP Import, Q16, or similar fuels. Exposure can cause the injector's internal seal to swell, significantly reducing fuel flow.
Why are these 2150cc injectors easier to tune than many other large injectors?
Fuel Injector Clinic dynamically matches every injector using its proprietary Data Match Technology, greatly improving injector control in the sub-2 millisecond pulse width range. The result is excellent idle quality, improved part-throttle drivability, and more accurate ECU calibration despite the injector's massive flow capacity.
