Holley Sniper 556-173 Details

Upgrading to an MSD Flying Magnet Crank Trigger Kit will deliver the precise and reliable signal that a high performance engine requires. This kit gives you the ability to control timing electronically through a Holley EFI ECU (or other standalone engine management system / ignition controller). At the heart of the kit is the 3-wire Hall-Effect Sensor that is easier to set up, less susceptible to EMI/RFI interference/noise, and less likely to have false signals than other methods (Distributors and VR Magnetic Sensors). In addition, they are less prone to mechanical failure since there are no wear parts. With the included high quality timing pointer and the use of a direct bolt-on, degreed balancer (see application list for recommendations), you'll be able to adjust timing in the precise increments required for your engine.
