    Holley Sniper 565-345 Details

    HyperSpark Ready to Run adds plug and play ignition timing control to any Holley EFI system. This line of distributors comes with a built-in ignition coil driver, removing the need of mounting an ignition box or external coil driver. The design includes a single Hall Effect sensor providing engine rpm to the ECU. The precision shutter wheel design ensures accurate timing, even at very high engine speeds. They can also be used with other EFI systems that support a Hall Effect crank signal input.
