    Terminator X High Impedance Fuel Injectors feature a precision lapped disc valve, high-quality brass windings, and high-temp o-rings. These injectors provide excellent linearity with no discernible "bounce" at low pulse widths as commonly found in other injectors. With a wide variety of fuel flow offerings from 42 lb./hr. to 220 lb./hr. (441 cc/m to 2310 cc/m) you are sure to find an injector that matches your non-emissions controlled application. These high quality fuel injectors can also be used with any ECU that utilize high impedance fuel injector drivers.

    Description_INV KIT- FUEL INJECTOR 42 PPH, EIGHT PACK
    Description_ASC Designed for use in setups with a 38mm distance between the o-ring seats on the fuel rail and intake manifold (commonly referred to as an "LS3-Style" injector), this injector features a USCAR connector and 14mm o-rings on both ends. It is an ideal fit for Holley EFI Intake manifolds that include fuel rail brackets for shorter LS3/LS7 length injectors. However, when used in an intake manifold designed for factory LS3/LS7 injectors, the bottom o-ring needs to be replaced to ensure proper fitment.
