Holley Sniper EFI 565-303K HyperSpark Kit w/565-303 Ford Big Block

Our HyperSpark kits were designed to make upgrading your ignition on a Sniper 1 EFI equipped engine simple. When installed along with a new Sniper 1 EFI system, the combination creates the easiest conversion to install on the market, with only four connections required. Our harness only requires one connection to a switched power source, battery positive, battery negative, and fuel pump power. The pre-terminated connectors and a built in 40A relay provides power to all of the components within the system. With the main harness included, you’ll no longer need to run multiple wires to provide switched power for each individual component. Route the harness and pre-terminated connectors to your HyperSpark coil, distributor, and ignition box and plug them in.
