Features
Vehicle Compatibility and Return Conditions.
This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.
Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.
Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.
Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase. For assistance or clarification, please contact customer support.

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
