How to guide here - Technical Install Guide (updated EFI wiring, and fuel install guide coming soon)

Kit Includes:

  • Holley Sniper 2 EFI Self Learning TBI (black finish by default unless otherwise specified in order notes)
  • TWS Edelbrock performer intake, modified for TWS
  • Power Distribution Module for easy wiring
  • All the gaskets, clamps, air filter, linkage kit, stainless bolt kit, 160* thermostat, custom bleed nipple, and throttle cable
  • MSD Plug wires if you add the ignition kit

Optional add ons:

  • TWS Easy Return fuel system that makes use of your stock fuel pump setup (required if converting from carbs)
    • Cars with OEM EFI can either use the Easy Return system if their gas tank does not have a return by default, or use a replacement pump like this Upgrade Fuel Pump
  • Complete Holley Ignition system which consists of their Hyperspark distributor, coil, and ignition box that integrates directly into the Holley EFI for ultimate performance and tuning
  • Hyperspark plug and play wiring harness for super easy pairing of the Sniper EFI and Hyperspark components, includes MSD plug wires

Not only does this setup dramatically increase your drive ability, you can expect to see performance gains of up to 40-50 hp. With a set of TWS Performance headers and a TWS Performance cam kit you would be closer to 70hp gained over stock.
