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 Coil-Near-Plug smart ignition coils are designed for use with Holley HP and Dominator ECUs, as well other EFI systems that can drive "smart" ignition coils. Although they are engineered for high-powered race applications, they can be used on street-driven vehicles, as well. They are available individually (includes mating connector and pins) or in kits that include everything you need to upgrade your ignition.
Additional tech specs:
• Peak voltage: 44,000 V
• Peak output: 102 Mj
• Maximum battery voltage: 17.0 V
• Kits include coils, sub-harnesses, connectors, wires, and a wiring loom
Note: Upgrading a non-coil-near-plug main harness requires HLY-558-307 Holley universal coil-on-plug harness, sold separately, to complete the installation.
