Product Information

Product Details
Part No. 550-511-3PX-SBF
Warranty Details (2 YR REPLACEMENT IF DEFECTIVE)
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.

Product Features:
  • Sniper 2 Kit:
  • Power Distribution Module (PDM) was designed to keep your installation stress free by listing a wiring diagram to connect your system to the dedicated circuits
  • Ignition box keeps all the features of its predecessor in a smaller and lighter design, providing a clean installation, precise timing control, and consistent spark energy from idle to redline for optimal performance
  • Sniper 2 Bluetooth module turns your iOS or Android smartphone into a tuning and monitoring interface with a base map to get started and no laptop required
  • Patented clear installation cap eliminates confusion while installing the distributor with a marking indicator
  • Integrated transmission kick down provisions for GM TH350/400, 200R4/700R4 and Ford C4/C6 applications (Sniper 2 Transmission Control Kit and vehicle specific harnesses not included, both available separately)
  • Integrated ignition coil bracket simplifies mounting the ignition coil while delivering up to 150 mJ of spark energy per second from idle to redline
  • Supports up to 650 hp naturally aspirated or 575 hp boosted with (4) 100 lb./hr. injectors
  • HyperSpark Ignition:
  • Billet aluminum construction unit plugs directly into the main harness and features a Hall Effect crank trigger for a noise free RPM signal to the ECU
  • Sniper 2 EFI Bundle includes a Power Distribution Module (PDM), HyperSpark 2 ignition box, coil, and a Chevrolet or Ford distributor (depending on your application)
  • Only (4) wiring connections required; the Battery+, Battery-, Switched Ignition, and RPM
  • Available with or without fuel system, the complete fuel system consists of 20 ft. of 3/8 in. Vapor Guard fuel hose, fuel pump, fuel pressure regulator, filters, necessary hardware, and bulkhead fitting to return fuel into the tank
  • Next generation ECU features improved RF noise and interference resistance (protects against outdated car wiring, noisy alternators, faulty plug wires, etc.)
  • Geometrically redesigned throttle shaft and plate for a smoother throttle feel
  • Cast-in fuel crossover from the primary to secondary fuel rail
