Holley 550-510-3PK-SBC - Holley Sniper 2 EFI. Shiny. Master Kit. With PDM & GM/Chevy V8 Ignition Kit
The #1 selling EFI conversion just got better…again! We’re bundling our top selling Sniper 2 packages and passing along maximum savings! Available for small block Chevrolet, big block Chevrolet, and 8.2-inch deck small block Ford (5.0 base), these kits include a HyperSpark distributor, HyperSpark coil, and a HyperSpark 2 ignition box. Coupled with a 3.5” or 5" color LCD touchscreen handheld, Power Distribution Module (PDM), and either a base or master (in-line fuel system) Sniper 2 kit, these are the most complete Sniper EFI conversion kits ever offered by Holley. The PDM module was specifically designed to provide the easiest wiring experience for Sniper 2 kits that are paired with a HyperSpark ignition. Simply slide the stripped wire ends under the positive lock connector and tighten down the set screws. Battery power, ground, and a switched 12V source are all that's required from your vehicle to power the PDM and your Sniper 2 system. Make your classic drive like a modern fuel injected vehicle, including better cold starts, smooth drivability, and improved fuel economy. Sniper 2 was designed to be installed at home in your garage with limited tools and the support of Holley's comprehensive installation manuals and online videos. The handheld user-friendly setup wizard has you answer a few simple questions about your engine and the system will begin self-tuning with no laptop or tuning experience required. If you're looking for a high-performance fuel injection system that delivers power, efficiency, and ease of use, look no further than the Sniper 2 EFI system. Take complete control and make the conversion to EFI with a Sniper 2 EFI HyperSpark Ignition bundle.
