4 Channel Coil Driver Kit

The Holley 4 Channel Coil Driver Kit (Part 554-122) is a dedicated ignition control module designed for high-performance engine management and custom fuel injection tuning. This kit is suitable for various applications, including carbureted engine conversions and advanced EFI platforms with individually-controlled coil packs.

The 4-channel architecture independently controls four coil outputs, allowing for simultaneous firing or sequential spark scheduling based on the engine's configuration. Each channel is designed to manage coil saturation and discharge switching, ensuring consistent performance under load, which is essential for reliable engine operation.

Custom engine builders, turbo and supercharger conversions, and bracket-racing platforms can greatly benefit from this driver kit's flexibility and precision. Its compact design allows for easy installation in engine bays with limited space, and it integrates well with Holley ECUs and aftermarket tuning computers.
