Product Details

The Sniper EFI 550-511-3XK Sniper 2 EFI system represents the next generation of self-tuning electronic fuel injection, delivering professional-grade engine management in a sleek black finish. This all-new design features patent-pending technology that makes converting your carburetor to EFI easier than ever, with only four simple wiring connections required.

Key Features:

  • Supports up to 650 horsepower naturally aspirated or 575 horsepower on boost with four 100 lb/hr injectors
  • Redesigned injector connector for improved long-term reliability
  • Cast-in fuel crossover from primary to secondary fuel rail eliminates external plumbing
  • Onboard contactless magnetic TPS sensor ensures accurate throttle position readings
  • Redesigned throttle shaft and plate geometry delivers smoother throttle response
  • Hidden harness design with wiring exiting from rear of throttle body for clean engine bay appearance
  • Integrated transmission kickdown provisions for GM TH350/400, 200-4R/700R4 and Ford C4/C6 transmissions
  • Genuine Bosch LSU 4.9 wideband oxygen sensor provides real-time fuel map learning and tuning
  • Multiple inputs and outputs: 2x ground inputs, 2x ground outputs, 1x TPS output (0-5v), and 1x tach output

Simple Installation:

With only four wiring connections needed (Battery+, Battery-, Switched Ignition, and RPM), the Sniper 2 EFI eliminates the complexity typically associated with aftermarket fuel injection systems. The self-tuning capability means the system learns and adjusts your fuel map automatically as you drive, delivering optimal performance without extensive tuning knowledge.
