Description

Holley EFI Terminator X fuel injectors feature a precision lapped disc valve, high-quality brass windings, and high-temperature 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. you are sure to find an injector that matches your non-emissions-controlled application. Holley EFI Terminator X fuel injectors can also be used with any ECU that utilize high-impedance fuel injector drivers.

Features:

* PICO/EV6-style performance injectors are sold individually or in a set of 8
* High impedance for use with saturated drivers
* Rated injector flow 220 lb./hr. at 43 psi of base fuel pressure
* USCAR injector connector
* 40mm O-ring to O-ring length
* Compatible with many OEM LS intake manifolds
* Easy to install in any Holley EFI Hi-Ram intake, using Holley fuel rail adapter kit
