-10% Terminator X Fuel Injector, High Impedance, 220 lb/hr

Holley introduced the Terminator X line of fuel injectors to meet two vacacies in their product line.  First, it fills the need for a 38mm-long (LS3/EV6) style injector.  Second, it solves the lack of a high-flowing high-impedance injector above the 48 PPH level in Holley's LS1/EV1-style injectors.  This fuel injector is intended for applications with 38mm between the o-ring seat on the fuel rail and the o-ring seat on the intake manifold (often referred to as an "LS3-Style" injector.)  It features a USCAR connector.  O-rings are sized for a 14mm o-ring boss on both ends. This injector is a perfect fit for Holley EFI Intake manifolds that include fuel rail brackets for shorter LS3/LS7 length injectors.  However, to use these in an intake manifold designed for factory LS3 / LS7 injectors the bottom o-ring will need to be swapped.  See below for additional product attributes.
