| The Best Injectors on the Market. Period.
FAST Precision-Flow™ fuel injectors deliver the super-efficient fuel delivery that high horsepower EFI engines demand. Engineered to yield faster throttle response and superior fuel atomization, FAST™ injectors are manufactured to the tightest tolerances in the industry and are flow certified to ensure consistent performance.
High vs Low Impedance Injectors
As a general rule, you will need to run high-impedance injectors whenever you retain your factory Engine Control Unit (ECU). Failure to use high-impedance injectors with a factory EFI computer will cause severe damage to it. FAST™ offers high-impedance injectors up to 60 lb/hr, so we’ve got you covered for nearly any performance scenario where you would still want to use your factory computer. For an aftermarket ECU, like the FAST™ XFI™ system, low-impedance injectors, available up to 160 lb/hr, are the way to go.
NOTE: fuel injectors in and of themselves do nothing to produce power, so don’t choose a larger injector because of the peak HP rating of the injector –too large of an injector will only waste fuel and hurt your throttle response.

These injectors will only work with LT1 fuel rails if you either A) modify the injector where the injector-to-rail retainer clip slides in place or B) eliminate the clip all together.
